Anti-MARK4 antibodies are used in the immunodetection of the protein microtubule affinity regulating kinase 4. In humans, the canonical protein has a reported length of 752 amino acid residues and a mass of 82.5 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the CAMK Ser/Thr protein kinase protein family, MARK4 is known to be involved with the cell cycle. Post-translational modifications have been described, including ubiquitination and phosphorylation. Synonyms for this target antigen include MAP/microtubule affinity-regulating kinase like 1, MARK4 serine/threonine protein kinase, epididymis secretory sperm binding protein, and MAP/microtubule affinity-regulating kinase 4. MARK4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of MARK4 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
