Target data

Molecular adapter required for selective macroautophagy (aggrephagy) by acting as a bridge between polyubiquitinated proteins and autophagosomes (PubMed : 15340068, PubMed : 15953362, PubMed : 16286508, PubMed : 17580304, PubMed : 20168092, PubMed : 22017874, PubMed : 22622177, PubMed : 24128730, PubMed : 28404643, PubMed : 29343546, PubMed : 29507397, PubMed : 31857589, PubMed : 33509017, PubMed : 34471133, PubMed : 34893540, PubMed : 35831301, PubMed : 37306101, PubMed : 37802024). Promotes the recruitment of ubiquitinated cargo proteins to autophagosomes via multiple domains that bridge proteins and organelles in different steps (PubMed : 16286508, PubMed : 20168092, PubMed : 22622177, PubMed : 24128730, PubMed : 28404643, PubMed : 29343546, PubMed : 29507397, PubMed : 34893540, PubMed : 37802024). 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 (PubMed : 15911346, PubMed : 20168092, PubMed : 22017874, PubMed : 24128730, PubMed : 29343546, PubMed : 29507397, PubMed : 31857589, PubMed : 37802024). 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 (PubMed : 16286508, PubMed : 17580304, PubMed : 20168092, PubMed : 22622177, PubMed : 24128730, PubMed : 28404643, PubMed : 37802024). SQSTM1 is itself degraded along with its ubiquitinated cargos (PubMed : 16286508, PubMed : 17580304, PubMed : 37802024). Also required to recruit ubiquitinated proteins to PML bodies in the nucleus (PubMed : 20168092). Also involved in autophagy of peroxisomes (pexophagy) in response to reactive oxygen species (ROS) by acting as a bridge between ubiquitinated PEX5 receptor and autophagosomes (PubMed : 26344566). Acts as an activator of the NFE2L2/NRF2 pathway via interaction with KEAP1 : interaction inactivates the BCR(KEAP1) complex by sequestering the complex in inclusion bodies, promoting nuclear accumulation of NFE2L2/NRF2 and subsequent expression of cytoprotective genes (PubMed : 20452972, PubMed : 28380357, PubMed : 33393215, PubMed : 37306101). Promotes relocalization of 'Lys-63'-linked ubiquitinated STING1 to autophagosomes (PubMed : 29496741). 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 (PubMed : 27368102, PubMed : 33472082). Sequesters tensin TNS2 into cytoplasmic puncta, promoting TNS2 ubiquitination and proteasomal degradation (PubMed : 25101860). May regulate the activation of NFKB1 by TNF, nerve growth factor (NGF) and interleukin-1 (PubMed : 10356400, PubMed : 10747026, PubMed : 11244088, PubMed : 12471037, PubMed : 16079148, PubMed : 19931284). May play a role in titin/TTN downstream signaling in muscle cells (PubMed : 15802564). Adapter that mediates the interaction between TRAF6 and CYLD (By similarity).
