Neuroprotection by the NR3A subunit of the NMDA receptor.
Hyperactivation of NMDA-type glutamate receptors (NMDARs) results in excitotoxicity, contributing to damage in stroke and neurodegenerative disorders. NMDARs are generally comprised of NR1/NR2 subunits but may contain modulatory NR3 subunits. Inclusion of NR3 subunits reduces the amplitude and dramatically decreases the Ca2+ permeability of NMDAR-associated channels in heterologous expression s...
متن کاملCharacterization of a soluble ligand binding domain of the NMDA receptor regulatory subunit NR3A.
NR3A is expressed widely in the developing CNS of mammals. Coassembly of NR3A with NR1 and NR2 modifies NMDA receptor-mediated responses, reducing calcium permeability and single-channel conductance. The ligand binding properties of NR3A are unknown but shape the role NR3A plays when incorporated into NMDA receptors. Here, a soluble NR3A ligand binding domain (NR3A S1S2) was constructed based o...

The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that in association with Raptor, mLST8, PRAS40 and Deptor forms a complex (mTORC1) playing the key role in the regulation of protein biosynthesis, transcription, cellular metabolism, apoptosis and autophagy; mainly via direct phosphorylation of S6 kinases. mTORC1 is activated by growth factors and amino acids via the activati...

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
15 صفحه اولAssembly with the NR1 subunit is required for surface expression of NR3A-containing NMDA receptors.
Functional NMDA receptors are heteromultimeric complexes of the NR1 subunit in combination with at least one of the four NR2 subunits (A-D). Coexpression of NR3A, an additional subunit of the NMDA receptor family, modifies NMDA-mediated responses. It is unclear whether NR3A interacts directly with NR1 and/or NR2 subunits and how such association might regulate the intracellular trafficking and ...
