Anti-LMTK3 antibodies are used in the immunodetection of the protein lemur tyrosine kinase 3. In humans, the canonical protein has a reported length of 1460 amino acid residues and a mass of 153.7 kDa. Its subcellular localization is in the Golgi and membrane. It is notably expressed in many tissues, such as the adrenal gland and caudate. A member of the Tyr protein kinase protein family, LMTK3 is reported to be a protein kinase, which phosphorylates ESR1 (in vitro) and protects it against proteasomal degradation. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include serine/threonine-protein kinase LMTK3 and protein phosphatase 1, regulatory subunit 101. LMTK3 gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Some LMTK3 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.
