{"product_id":"nsj-fy12546-100ug","title":"BCAP31 Antibody \/ B-cell receptor-associated protein 31, 100 ug","description":"\u003cp\u003eBCAP31 antibody detects B-cell receptor-associated protein 31, an integral endoplasmic reticulum (ER) membrane protein that functions as a chaperone and adaptor in protein trafficking and apoptosis regulation. BCAP31 is a member of the BCAP31 family, which includes BCAP29, and plays crucial roles in protein quality control, ER-Golgi transport, and caspase-mediated cell death. The BCAP31 antibody is used in cell biology and immunology research to study membrane trafficking, ER stress, and apoptotic signaling.\u003cbr\u003e\u003cbr\u003eBCAP31 is encoded by the BCAP31 gene located on the X chromosome (Xp22.13). The protein is approximately 28 kilodaltons and contains three transmembrane domains with a cytoplasmic C-terminal tail that interacts with diverse partners, including BCL2 and procaspase-8. These interactions position BCAP31 at the intersection of the secretory and apoptotic pathways, integrating ER homeostasis with cell death regulation.\u003cbr\u003e\u003cbr\u003eThe BCAP31 antibody detects a 28 kilodalton band on western blot and shows reticular ER staining consistent with its localization. BCAP31 forms complexes with chaperones such as calnexin and Sec61, assisting in the folding and export of glycoproteins from the ER to the Golgi apparatus. It also mediates ER retention or degradation of misfolded proteins, linking it to the unfolded protein response (UPR).\u003cbr\u003e\u003cbr\u003eIn apoptosis, BCAP31 acts as a substrate for caspase cleavage, generating pro-apoptotic fragments that amplify death signaling through mitochondria. This dual role allows BCAP31 to serve as both a quality control checkpoint and a stress sensor. Mutations or deletions of BCAP31 cause X-linked intellectual disability syndromes characterized by developmental delay and hearing loss, emphasizing its importance in neuronal maintenance.\u003cbr\u003e\u003cbr\u003eBCAP31 also contributes to immune cell signaling and antigen presentation by modulating trafficking of MHC class I molecules. NSJ Bioreagents provides a validated BCAP31 antibody optimized for western blot, immunofluorescence, and ER-Golgi transport analysis, supporting research into protein folding, apoptosis regulation, and membrane trafficking.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug","offer_id":48537696370912,"sku":"FY12546","price":449.0,"currency_code":"KRW","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/9330\/8896\/files\/get_image_ed47b63c-07c4-43e2-870d-f9a3fe598af3.jpg?v=1768353652","url":"https:\/\/rndmate.com\/products\/nsj-fy12546-100ug","provider":"알앤디메이트","version":"1.0","type":"link"}
