Microtubule associated proteins 1B and 1S : interactions with NR1 and NR3A

Björklund, Stefan January 2008 (has links)
<p> </p><p>In previous studies the carboxyl-terminus of microtubule-associated protein 1S was shown to interact with the <em>N</em>-methyl-D-aspartate receptor subunit NR3A (Eriksson <em>et. al.</em>)<sup>1</sup>.  In this study, interactions between three truncations of the microtubule-associated proteins 1B and one truncation of the microtubule-associated protein 1S carboxyl-terminus and the <em>N</em>-methyl-D-aspartate receptor subunits NR1 and NR3A were examined. The study showed that an interaction occurred between amino acids 2167 to 2365 of the microtubule-associated protein 1B and NR3A.  That region of microtubule associated protein 1B corresponds to a microtubule-binding region in the light chain. It has been shown in earlier studies (Reviewed in Halpain S. <em>et a1<sup>2</sup></em>, Riederer, BM<em>.  et.al<sup>3</sup></em>.) that the light chain is a active part of the protein that have been post translational cleaved. The MAP 1 proteins are present in all tissue but has higher concentrations in the Post Synaptic Density of neurons in the central nervous system.  The <em>N</em>-methyl-D-aspartate receptors are present in glial cells and in the dendritic shafts of the central nervous system neurons (Eriksson <em>et. al.</em>)<sup>1 </sup>. The diseases were these proteins may play a part is mainly memory destructive diseases such as Alzheimers disease and in muscular dystrophy, but these assumptions are still being speculated.</p><p> </p>

In previous studies the carboxyl-terminus of microtubule-associated protein 1S was shown to interact with the N-methyl-D-aspartate receptor subunit NR3A (Eriksson et. al.)1.  In this study, interactions between three truncations of the microtubule-associated proteins 1B and one truncation of the microtubule-associated protein 1S carboxyl-terminus and the N-methyl-D-aspartate receptor subunits NR1 and NR3A were examined. The study showed that an interaction occurred between amino acids 2167 to 2365 of the microtubule-associated protein 1B and NR3A.  That region of microtubule associated protein 1B corresponds to a microtubule-binding region in the light chain. It has been shown in earlier studies (Reviewed in Halpain S. et a12, Riederer, BM.  et.al3.) that the light chain is a active part of the protein that have been post translational cleaved. The MAP 1 proteins are present in all tissue but has higher concentrations in the Post Synaptic Density of neurons in the central nervous system.  The N-methyl-D-aspartate receptors are present in glial cells and in the dendritic shafts of the central nervous system neurons (Eriksson et. al.)1 .
