Anti-ASIP antibodies are used in the immunodetection of the protein agouti signaling protein. In humans, the canonical protein has a reported length of 132 amino acid residues and a mass of 14.5 kDa. It has been described to be a secreted protein. It is reported to be expressed in adipose tissue, testis, ovary and heart and at lower levels in the liver, kidney and foreskin. ASIP is reported to be involved in regulation of melanogenesis. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include AGTI, AGTIL, ASP, SHEP9, agouti signaling protein, nonagouti homolog, and AGSW. ASIP gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for ASIP antibodies.
