Anti-insulinoma associated 1 antibodies enable researchers to detect and measure the insulinoma associated 1 antigen in biological samples. This target is a reported synonym of the INSM1 gene, which encodes INSM transcriptional repressor 1. This protein is known to function in the cell cycle and cell migration, among other biological roles. The human version of insulinoma associated 1 has a canonical amino acid length of 510 residues and a protein mass of 52.9 kilodaltons. It is reported to be localized in the nucleus of cells. Other names for this target antigen include IA-1, IA1, and insulinoma-associated protein 1.
