Anti-SRPK2 antibodies are used in the immunodetection of the protein SRSF protein kinase 2. In humans, the canonical protein has a reported length of 688 amino acid residues and a mass of 77.5 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in the brain, moderately expressed in the heart and skeletal muscle and at low levels in the lung, liver, and kidney. A member of the CMGC Ser/Thr protein kinase protein family, SRPK2 is known to be involved with angiogenesis and cell differentiation. Synonyms for this target antigen include SFRS protein kinase 2, SR protein kinase 2, SR-protein-specific kinase 2, serine kinase SRPK2, serine/arginine-rich protein-specific kinase 2, and SFRSK2. SRPK2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of SRPK2 antibodies have been mentioned in research publications and have associated citations. Immunohistochemistry is a widely used application for these antibodies. ELISA, Western Blot, and Immunofluorescence are also common applications.
