Anti-ALMS1 centrosome and basal body associated protein antibodies are used for the immunodetection of the protein encoded by the ALMS1 gene. In humans, the canonical protein has a reported length of 4168 amino acid residues and a mass of 461.1 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. It is reported to be expressed in all tissues tested including adipose and pancreas. A member of the ALMS1 protein family, it is known to be involved in PCM1-dependent intracellular transport. The gene encoding this protein is implicated in Alstrom syndrome. Other names for this target antigen include centrosome-associated protein ALMS1, Alstrom syndrome 1, Alstrom syndrome protein 1, and ALSS. Gene orthologs have been identified in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species.
