Anti-SPTY2D1 antibodies are used in the immunodetection of the protein SPT2 chromatin protein domain containing 1. In humans, the canonical protein has a reported length of 685 amino acid residues and a mass of 75.6 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the SPT2 protein family, SPTY2D1 is reported to be a histone chaperone that stabilizes pre-existing histone tetramers and regulates replication-independent histone exchange on chromatin. Synonyms for this target antigen include SPT2 domain-containing protein 1, SPT2, Suppressor of Ty, domain containing 1, and protein SPT2 homolog. SPTY2D1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Immunocytochemistry and Immunohistochemistry are common applications for SPTY2D1 antibodies.
