Anti-MTSS I-BAR domain containing 1 antibodies are used for the immunodetection of the protein encoded by the MTSS1 gene. In humans, the canonical protein has a reported length of 755 amino acid residues and a mass of 82.3 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 4 different isoforms for this protein. It is reported to be expressed in many tissues, including spleen, thymus, prostate, testis, uterus, colon, and peripheral blood. A member of the MTSS protein family, it is believed to be related to cancer progression or tumor metastasis in a variety of organ sites, most likely through an interaction with the actin cytoskeleton. Other names for this target antigen include MIMA, MIMB, protein MTSS 1, MTSS1, I-BAR domain containing, metastasis suppressor 1, and MIM. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species.
