This data was developed using the same antibody in a different buffer formulation (ab211324).

ab211324 was shown to react with SQSTM1 in wild-type U-2 OS cells in Western blot with loss of signal observed in a SQSTM1 knockout cell line. Wild-type U-2 OS and SQSTM1 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab211324 overnight at 4 °C at a 1/1000 dilution. Blots were incubated with goat anti-rabbit HRP secondary antibodies at 0.2ug/mL before imaging. These data were provided by YCharOS Inc., an open science company with the mission of characterizing commercially available antibody reagents for all human proteins. Abcam and YCharOS are working together to help address the reproducibility crisis by enabling the life science community to better evaluate commercially available antibodies.

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).
