Additional Information

Alternative name: sequestosome-1 (SQSTM1, ubiquitin-binding protein p62, p60, EBIAP, PDB3, ZIP3)

UniProt: Q13501

Immunogen: A synthetic peptide as a part of sequestosome-1 (ubiquitin-binding protein p62, p60, EBIAP) conjugated to immunogenic carrier protein has been used as the immunogen.

Format: Lyophilized

Isotype: IgG

Description: FUNCTION: Adapter protein which binds ubiquitin and may regulate the activation of NFKB1 by TNF-alpha, nerve growth factor (NGF) and interleukin-1. May play a role in titin/TTN downstream signaling in muscle cells. May regulate signaling cascades through ubiquitination. May be involved in cell differentiation, apoptosis, immune response and regulation of K(+) channels. SUBCELLULAR LOCATION: Cytoplasm. Late endosome. Nucleus. Note=Sarcomere. In cardiac muscles localizes to the sarcomeric band. Localizes to late endosomes. May also localize to the nucleus. Accumulates in neurofibrillary tangles and in Lewy bodies of neurons from individuals with Alzheimer and Parkinson disease respectively. Enriched in Rosenthal fibers of pilocytic astrocytoma. In liver cells, accumulates in Mallory bodies associated with alcoholic hepatitis, Wilson disease, indian childhood cirrhosis and in hyaline bodies associated with hepatocellular carcinoma. TISSUE SPECIFICITY: Ubiquitously expressed. Also known as: Sequestosome 1, phosphotyrosine-independent ligand for the Lck SH2 domain of 62 kDa, ubiquitin-binding protein p62, EBI3-associated protein of 60 kDa, p60, EBIAP, SQSTM1, A170, OSIL, PDB3, ZIP3, p62B.

Specificity: Appears to be specific for sequestosome-1.

Application Details

Application Notes: IHC (both on frozen and paraffin embedded tissues), WB. Use at a concentration of 10-50 µg/ml. The optimal concentration should be determined by the end user.

Purity: IgG

Storage: Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.

Restrictions: For Research Use only
