Anti-TESK1 antibodies are used in the immunodetection of the protein testis associated actin remodelling kinase 1. In humans, the canonical protein has a reported length of 626 amino acid residues and a mass of 67.7 kDa. Its subcellular localization is in the cytoplasm. It is reported to be expressed in podocytes and renal tubular cells in the kidney. A member of the TKL Ser/Thr protein kinase protein family, TESK1 is known to be involved with cytoskeleton organization and protein phosphorylation. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include testicular protein kinase 1, testis-specific kinase 1, and dual specificity testis-specific protein kinase 1. TESK1 gene orthologs have been reported in the mouse, rat, bovine, zebrafish and chicken species. A number of TESK1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
