Anti-POMK antibodies are used in the immunodetection of the protein protein O-mannose kinase. In humans, the canonical protein has a reported length of 350 amino acid residues and a mass of 40.1 kDa. Its subcellular localization is in the ER. A member of the Ser/Thr protein kinase protein family, it is known to be involved with brain development and protein phosphorylation. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include probable inactive protein kinase-like protein SgK196, protein kinase-like protein SgK196, and Sugen kinase 196.
