Asf2 Mediates Sir3 Availability During the Assembly of HeterochromatinStephenson, Sean E. K. 07 January 2022 (has links)
Heterochromatin in S. cerevisiae is formed at telomeres, rDNA, and the mating type loci by the Silent Information Regulator (SIR) complex. Silencing requires the SIR complex that consists of Sir2, Sir3, and Sir4. The SIR proteins interact with each other, nucleosomes, and DNA binding proteins that are located at silencers. Although the interactions within the SIR complex are well defined, the requirements for each of these interactions during the nucleation and spreading of heterochromatin are not. This study uses genetic and biochemical techniques to assess silencing at various loci and to detect interactions between the SIR proteins. Asf2 (Anti-Silencing Factor 2) is a poorly characterized protein that interacts with Sir3 and is investigated in detail throughout this work. The overexpression of ASF2 disrupts silencing and does so by outcompeting Sir4 for Sir3 binding. ASF2 is a paralog of SIR4, and they share significant homology within their coiled-coil domains which is required for their interaction with Sir3. The Asf2 protein exists as a dimer that depends on Sir3 and may serve as a tool to alter Sir3 availability and impact heterochromatin stability. The evidence presented here categorizes the requirements for the Sir3-Sir4 interaction and the establishment of H4K16 acetylation in nucleation and spreading. Mutations in the AAA+ domain of Sir3 (sir3-4A) render it insufficient to nucleate heterochromatin but do not prevent Sir3-4A and Sir4 from spreading downstream of silencers. The Sir3-Sir4 interaction is therefore a nucleation-specific requirement. Cells lacking SAS2 are defective for telomere silencing, but silencing is partially restored by overexpressing SIR3 but not sir3-4A. Although the Sir3-Sir4 interaction is not required for Sir3 to spread on its own, Sir4/Sir2 are unable to spread without the establishment of H4K16 acetylation.

The county of Surrey and the English RevolutionGurney, John January 1991 (has links)
The aim of this thesis is to provide a study of political conflict and local-national relations during the English Revolution, in the context of the county of Surrey, a county in which a moderate parliamentarian administration was able to survive until 1649. The thesis concentrates in particular on political developments in the period from 1640 to 1653. The character of local society in Surrey before 1640 is examined in Chapter One, as are relations between the Surrey gentry and the government of Charles I. The importance of localism is emphasised, despite the cosmopolitan nature of society in the county. Political and religious developments in Surrey between the autumn of 1640 and the, end of 1642 are examined in Chapter Three; Chapter Four provides a study of patterns of civil war allegiance in the county. In Chapters Five and Six, political conflicts from 1642 to 1646 are studied, and in particular the campaign to remove Sir Richard Onslow and his associates from their dominant position in local administration. It is argued that parliament's sensitivity to localism helped to ensure Onslow's political survival during the 1640's. The Surrey petitioning movement of 1648, the Earl of Holland's rising, and local reactions to the establishment of the Commonwealth in 1649, are discussed in Chapter Six, The final chapter provides a study of the Surrey Digger movement, and of social conflict in the county during the civil war and after. Although it is clear that the Diggers met with considerable opposition in Walton, it is suggested that there was some sympathy for them in Cobham, and that they should not be dismissed as outsiders in that parish.

The Satirical Elements in the Works of Sir John VanbrughHanicak, Helen W. 01 1900 (has links)
The purpose of this paper is to demonstrate through an examination of the satirical elements in Sir John Vanbrugh's eight complete plays and his fragmentary last play that his central motivating force was a desire to entertain London society and divert them from "their wives and taxes."

Modern Trends in the Interpretation of FalstaffBoswell, Fred Page 08 1900 (has links)
The different interpretations of the character of Sir John Falstaff have been so controversial that at no time since the presentation of the Henry IV plays have critics been able to agree as to his precise qualities. He has been called the greatest humorous character in all literature by even those critics who have spoken adversely of his other traits. George Bernard Shaw called him "a besotted and disgusting old wretch," an opinion added to those of others who have seen him as a coward, liar, cheat, thief, glutton, and rogue. There is no denying that he is one of the most captivating and controversial of all characters in English literature.

The Binding Girdle: TrawÞe and Gift Exchange in Sir Gawain and the Green KnightSearcy, Deborah W. 01 January 2007 (has links)
Integrating chivalric romance narrative with complicated instances of pre-modern exchange, Sir Gawain and the Green Knight reveals the binding power of pledging one?s trawþe and the transformative power of exchanged objects in a gift economy. By reading the Exchange of Blows and the Exchange of Winnings according to the social demands of a gift economy and of a pledged trawþe, this thesis delineates the nature of Gawain?s failure to keep his word to his host. I offer my analysis of gift theory to suggest how the poem reveals the tensions between chivalric pledges of loyalty and nascent capitalist exchanges. R. A. Shoaf demonstrates the presence in the text of an emerging commercial economy, claiming the poem ?involves the transformation of Gawain?into a consumer and?into a merchant? (3-4). While Gawain behaves as a nascent capitalist, as evident by his passive reception of the exchanged items and his lack of generosity, the other residents of Hautdesert do not. The workings of gift exchange were first postulated by social anthropologists: Marcel Mauss focused on reciprocity, while Branislaw Malinowski, and later, Annette Weiner, argued that gift exchanges operate in a circular system, with repayment not necessarily directed toward the original donor. The exchanges between Bertilak and Gawain show elements of the requisite reciprocity of Mauss? formulation, yet the presence of Morgan le Fey and Lady Bertilak complicates the exchanges and suggests an economy of circularity. While Geraldine Heng and Sheila Fischer have argued that the women of the text exhibit agency?Morgan initiates the Exchange of Blows and Lady Bertilak gives kisses and the girdle?this project argues that it is the performative presence of the trawþe between Gawain and Bertilak that creates a male bond, ultimately denying the women authority. The trawþe circumscribes Morgan?s control and allows for the exchange of Lady Bertilak as an object. Richard Firth Green addresses the late medieval tensions in the semantic definitions of ?truth,? arguing that ?in an oral society the precise words of the oath?bind the speaker and listener by virtue of an inherent performative power? (60). While Gawain functions as a self-interested capitalist, keeping the girdle for its value to save his life, the chivalric trawþe ensures that failure to adhere to the terms of the agreement results not only in contractual liability but knightly disgrace. Gawain?s failure to reciprocate the gift leads to his dishonor, for the medieval gift that is not reciprocated ?would make the recipient dependent on the donor,? endangering ?his honour, freedom and even his life? (Gurevich 180). In medieval gift systems the values of exchanged objects are determined not only by their function within a competitive game about prestige and power, but also by their identification with the donors themselves. Annette Weiner?s articulation of the inalienability of certain objects?the possibility that some objects are ?kept? despite apparent exchange?is useful in explaining the significance of the girdle in Gawain?s failure. Weiner explains that what ?makes a possession inalienable is its exclusive and cumulative identity with a particular series of owners through time? (Weiner 33). The girdle presents just such an inalienable possession; Bertilak ?keeps? the girdle despite Gawain?s physical possession of it. Gawain remains indebted to his adversary, and although he is released from his trawþe, he will continue to wear the girdle as a sign of his failure and the bond with the Green Knight. Ultimately, the court of Camelot assumes the sign of the green girdle, a subtle warning by the Gawain-poet of the inevitable spread of un-trawþe in prioritizing the values of self-interested capitalist exchange.

Food, Sex and Violence : Carnival in Sir Gawain and the Green KnightAndersson, Tobias January 2011 (has links)
This essay discusses the aspects of Carnival in the poem Sir Gawain and the Green Knight and the opposition between ordinary official life and the Carnival. Peter Burke’s and Mikhail Bakhtin’s theories on the Carnival are used throughout the analyse of the poem mainly with focus on four different aspects; food, sex, violence and games. The essay also discusses the questioning of rank, which was central to the spirit of the Carnival where all were considered equal. Gawain is the protagonist who throughout the poem manages to resist the spirit of the Carnival despite being challenged by three different antagonists who in their on ways symbolise the Carnival; the Green knight with aggressive and mocking speech, the Lady of the Castle who acts as the seducer and Lord Bertilak who in his three hunts shows that he embraces the spirit of the Carnival.
