Anti-small ArfGAP 1 antibodies are used for the immunodetection of the protein encoded by the SMAP1 gene. In humans, the canonical protein has a reported length of 467 amino acid residues and a mass of 50.4 kDa. Its subcellular localization is in the cell membrane. Alternative splicing is reported to yield 3 different isoforms for this protein. It is notably expressed in bone marrow, adrenal gland, trachea, lymph node, spinal cord, peripheral blood leukocytes, thyroid and stomach. It is noted to be involved in the regulation of cell differentiation. Other names for this target antigen include stromal membrane-associated protein 1 and stromal membrane-associated GTPase-activating protein 1. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some small ArfGAP 1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
