SQSTM1
SQSTM1 (Sequestosome-1) is a gene. The public catalogues list it as a fusion partner, and the evidence so far is association rather than a proven role. Tied to Sarcomas and Osteosarcoma. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
Molecular adapter required for selective macroautophagy (aggrephagy) by acting as a bridge between polyubiquitinated proteins and autophagosomes. Promotes the recruitment of ubiquitinated cargo proteins to autophagosomes via multiple domains that bridge proteins and organelles in different steps. SQSTM1 first mediates the assembly and removal of ubiquitinated proteins by undergoing liquid-liquid phase separation upon binding to ubiquitinated proteins via its UBA domain, leading to the formation of insoluble cytoplasmic inclusions, known as p62 bodies. SQSTM1 then interacts with ATG8 family proteins on autophagosomes via its LIR motif, leading to p62 body recruitment to autophagosomes, followed by autophagic clearance of ubiquitinated proteins. SQSTM1 is itself degraded along with its ubiquitinated cargos. Also required to recruit ubiquitinated proteins to PML bodies in the nucleus. Location: Cytoplasmic vesicle, autophagosome; Preautophagosomal structure; Cytoplasm, cytosol; Nucleus, PML body (UniProt). Locus 5q35.3 (HGNC).
