Alpha B chain crystallins (αBC) can be induced by heat shock, ischemia, and oxidation, and are members of the small heat shock protein (sHSP also known as the HSP20) family. They act as molecular chaperones although they do not renature proteins and release them in the fashion of a true chaperone; instead, they bind improperly folded proteins to prevent protein aggregation. Furthermore, αBC may confer stress resistance to cells by inhibiting the processing of the pro-a… WebTo analyze the conformational features and aggregation properties of the mutant protein E107A human γD-crystallin (HGDC), associated with congenital nuclear cataract. cDNAs of wild type and E107A mutant were cloned and expressed in BL21 (DE3) pLysS WebJul 29, 2024 · Methods: SNPs in the introns of crystallin gene family - CRYAA (rs3788059), CRYAB (rs2070894), CRYBA4 (rs2071861), and CRYBB2 (rs5752083, rs5996863) - were genotyped in 248 participants consisting ... how morphine converts to herion carbolation
