Anti-TOPK antibodies enable researchers to detect and measure the TOPK antigen in biological samples. This target is a reported synonym of the PBK gene, which encodes PDZ binding kinase. This protein is known to function in the cell cycle and peptidyl-serine phosphorylation, among other biological roles. The human version of TOPK has a canonical amino acid length of 322 residues and a protein mass of 36.1 kilodaltons, although 2 isoforms have been identified. It is reported to be notably expressed in the placenta and testis. TOPK is a member of the STE Ser/Thr protein kinase protein family. Western Blot is the most common application for the TOPK antibodies listed below. ELISA and Immunohistochemistry are also common applications.
