Anti-polo like kinase 5 antibodies enable researchers to detect and measure the polo like kinase 5 antigen in biological samples. This target is a reported synonym of the PLK5 gene, which encodes polo like kinase 5 (inactive). This protein is known to function in the cell cycle and cell differentiation, among other biological roles. The human version of polo like kinase 5 has a canonical amino acid length of 336 residues and a protein mass of 36.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and notably expressed in the testis, nasopharynx, fallopian tube, and bronchus. polo like kinase 5 is a member of the Ser/Thr protein kinase protein family. Some polo like kinase 5 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunofluorescence is also a common application.
