SQSTM1/p62 Antibody

SQSTM1(Sequestosome 1)/p62 is an adapter protein which binds ubiquitin and regulates signaling cascades through ubiquitination. It functions as a bridge between polyubiquitinated cargo and autophagosomes and interacts directly with both the cargo to become degraded and an autophagy modifier of the MAP1 LC3 family.  Along with WDFY3, SQSTM1 is involved in the formation and autophagic degradation of cytoplasmic ubiquitin-containing inclusions (p62 bodies, ALIS/aggresome-like induced structures) and is required to recruit ubiquitinated proteins to PML bodies in the nucleus. It may regulate the activation of NFKB1 by TNF-alpha, nerve growth factor (NGF) and interleukin-1 and may play a role in titin/TTN downstream signaling in muscle cells. It is an adapter that mediates the interaction between TRAF6 and CYLD.  SQSTM1 may be involved in cell differentiation, apoptosis, immune response and regulation of K(+) channels. It is involved in endosome organization by retaining vesicles in the perinuclear cloud: following ubiquitination by RNF26, attracts specific vesicle-associated adapters, forming a molecular bridge that restrains cognate vesicles in the perinuclear region and organizes the endosomal pathway for efficient cargo transport. Mutations in this gene result in frontotemporal dementia and/or amyotrophic lateral sclerosis, and familial Paget disease of bone.  Anti-SQSTM1 Antibody is useful for researchers interested in Cancer Research, Neuroscience, and Cytokines & Growth Factor Antibodies.
