Anti-ITPKA antibodies are used in the immunodetection of the protein inositol-trisphosphate 3-kinase A. In humans, the canonical protein has a reported length of 461 amino acid residues and a mass of 51 kDa. Its subcellular localization is in the cytoplasm. It is reported to be expressed in the brain. A member of the Inositol phosphokinase (IPK) protein family, ITPKA is known to catalyze the phosphorylation of 1D-myo-inositol 1,4,5-trisphosphate (InsP3) into 1D-myo-inositol 1,3,4,5-tetrakisphosphate and participates to the regulation of calcium homeostasis. Synonyms for this target antigen include IP3KA, IP3 3-kinase A, IP3K A, inositol 1,4,5-trisphosphate 3-kinase A, insP 3-kinase A, and IP3-3KA. ITPKA gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of ITPKA antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
