Anti-INCA1 antibodies are used in the immunodetection of the protein inhibitor of CDK, cyclin A1 interacting protein 1. In humans, the canonical protein has a reported length of 236 amino acid residues and a mass of 26.8 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the testis, and at lower levels in ovary. A member of the INCA protein family, INCA1 is known to bind to CDK2-bound cyclins and inhibits the kinase activity of CDK2; binding to cyclins is critical for its function as CDK inhibitor. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include protein INCA1. INCA1 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. ELISA is a widely used application for the INCA1 antibodies listed below. In addition, Western Blot is also a common application.
