Anti-STAMBPL1 antibodies are used in the immunodetection of the protein STAM binding protein like 1. In humans, the canonical protein has a reported length of 436 amino acid residues and a mass of 49.8 kDa. Alternative splicing is reported to yield 2 different isoforms for this protein. It is ubiquitously expressed across many tissue types. A member of a the Peptidase M67C protein family, STAMBPL1 is reported to be a zinc metalloprotease that specifically cleaves 'Lys-63'-linked polyubiquitin chains. Synonyms for this target antigen include associated molecule with the SH3 domain of STAM (AMSH) - Family Protein, associated molecule with the SH3 domain of STAM (AMSH) like protein, and AMSH-like protease.
