Anti-ASB2 antibodies are used in the immunodetection of the protein ankyrin repeat and SOCS box containing 2. In humans, the canonical protein has a reported length of 635 amino acid residues and a mass of 70.2 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Ankyrin SOCS box (ASB) protein family, it is known to be involved with cytoskeleton organization and cardiac muscle cell differentiation. Post-translational modifications have been described, including ubiquitination and phosphorylation. Synonyms for this target antigen include ankyrin repeat and SOCS box protein 2 and ankyrin repeat and SOCS box-containing protein 2a.
