Not available outside of the UK & Ireland.

Application

Rabbit polyclonal anti-SQSTM1 antibody has been used:in immunoblottingin immunoprecipitationas a probe to determine the presence and roles of p62 protein/sequestosome 1 in processes such as autophagy

Biochem/physiol Actions

The p62 protein/sequestosome 1 (SQSTM1) is a multifunctional protein, which binds to ubiquitin. It acts as a scaffold protein for the nuclear factor kappa-B (NF-ΚB) signaling pathway. SQSTM1 also regulates apoptosis and autophagy. Mutations in this gene lead to sporadic and familial Paget disease of bone. It is also associated with protein aggregation diseases, such as Lewy bodies in Parkinson′s disease, neurofibrillary tangles in Alzheimer′s disease, and huntingtin aggregates. SQSTM1 is commonly found in inclusion bodies containing polyubiquitinated protein aggregates that accumulate in several degenerative diseases. p62 polymerizes through its N-terminal Phox and Bem1p (PB1) domain and interacts with polyubiquitinated proteins through its C-terminal ubiquitin-associated (UBA) domain. p62 acts as a linker between protein aggregates and the autophagy machinery.

General description

The p62 protein/sequestosome 1 (SQSTM1) comprises a Phox and Bem1p (PB1) domain at the NH2-terminal, a ZZ type zinc finger domain, a Pro, Glu, Ser, and Thr (PEST) region consisting of putative phosphorylation sites, and a ubiquitin-associated (UBA) domain at the COOH-terminal. The SQSTM1 gene is mapped to the human chromosome location 5q35.3.

Physical form

Solution in 0.01 M phosphate buffered saline pH 7.4, containing 15 mM sodium azide.

Specificity

Anti-p62/SQSTM1 (C-terminal) recognizes human, rat, and mouse p62/SQSTM1.

Storage and Stability

For continuous use, store at 2–8 °C for up to one month. For extended storage freeze in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.
