The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Identification and Characterization of the Interaction between VPS33B and SNAREsPuhacz, Michael 19 December 2011 (has links)
VPS33B is a Sec1/Munc18 protein required for the biogenesis of α-granules in megakaryocytes, which give rise to platelets. Mutations in VPS33B cause arthrogryposis, renal dysfunction and cholestasis (ARC) syndrome. Platelets from ARC patients completely lack α-granules, causing a bleeding disorder. VPS33B plays a role in vesicular fusion events through its interaction with the SNARE proteins, though no such interactions have been identified. Here, it is shown that VPS33B interacts with STX6, a member of the syntaxin subfamily of SNAREs. The introduction of ARC mutations into VPS33B completely abrogated binding to STX6. Confocal microscopy studies revealed STX6 co-localizes well with markers of the α-granule biogenesis pathway. This implies a role for the interaction of VPS33B with STX6 in α-granule biogenesis. Based on the known structure of STX6 and that predicted of VPS33B, suggests a novel and unique mode of binding between VPS33B and STX6 compared to other identified SM-STX pairs.
