Background Information
Sequestosome 1 (SQSTM1/p62) is a multifunctional adaptor protein implicated in selective autophagy, cell signaling pathways, and tumorigenesis. p62 has been implicated in shuttling ubiquitinated and sometimes aggregated proteins for autophagic degradation. As a autophagy-specific substrate, p62 is degraded during the autophagic process, which makes intracellular level of p62 as a marker for autophagy flux. p62 is at the cross-roads of several signaling pathways including Ras/ Raf/ MAPK and NFκB and plays important role in cancer. p62 is a component of inclusion bodies/ protein aggregates found in human diseases, including Huntington's disease, Alzheimer's disease, Parkinson's disease in the brain, and nephropathic cystinosis in kidney (PMID: 22074114, 22860231, 22714671). The molecular weight of p62 is predicted as 48/ 38 kDa, while western blot analyses using this antibody demonstrate the major band around 60-62 kDa in various tissues.

Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
FH Eleonora (Verified Customer) (04-12-2024) | The antibody unfortunately did not work in IF, no signal. In western blot the band is present but very faint.
|
FH David (Verified Customer) (01-13-2020) | Used for immunocytochemistry. Low signal in control cells, but very strong response when treated with bafilomycin A. Very obvious p62 puncta in cells.
