VAPB is an integral endoplasmic reticulum (ER) protein whose amino terminus projects into the cytosol. A proline to serine substitution at position-56 (VAPBP56S) leads to an autosomal-dominant form of amyotrophic lateral sclerosis (ALS), classified as ALS-8. (2). VAPB has been implicated in a variety of processes, including ER stress and the unfolded protein response (UPR), ER to Golgi transport, and bouton formation at the neuromuscular junction (1,2). The P56S mutation causes almost complete loss of function of VAPB to mediate UPR by inducing its misfolding and localization shift to non-ER compartments (1). A possible role of VAPB as a pathologic marker in PBMCs from ALS patients has been published (3).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nALS8; VAMP (vesicle-associated membrane protein)-associated protein B and C; VAMP associated protein B and C; VAMP-associated 33 kDa protein; VAMP-associated protein B; VAMP-associated protein B\/C; VAMP-associated protein C; VAMP-B; VAMP-B\/VAMP-C; VAMP-C; VAP-B; VAP-B\/VAP-C; VAP-C; VAPB; Vesicle-associated membrane protein-associated protein B\/C\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 27\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800045932713,"sku":"95339T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-95339t","provider":"Iright","version":"1.0","type":"link"}
