A portion of amino acids 432-540 from the human protein was used as the immunogen for the INSM2 antibody.
IA-6, also known as insulinoma-associated 2 or INSM2, is related to IA-1 (INSM1), a zinc-finger factor that is expressed in the developing nervous system. While the exact function of IA-6 is not known, other related insulinoma-associated proteins such as IA-2 are major autoantigens in type 1 diabetes. The homology exhibited by IA-6 to IA-1 has led to speculation that IA-6 may also play a role in the regulation of gene transcription. INSM2 may function as a growth suppressor or tumor suppressor in liver cells and in certain neurons.
