More info

The anti-proAKAP4 clone 6F12 recognizes the prodomain of A-kinase anchor protein 4 (AKAP4). This antibody is suitable for Western Blot, Immunofluorescence, Flow Cytometry and Immunohistochemistry.

This antibody was produced from a mouse hybridoma resulting from a mouse immunized with a peptide covering the prodomain of human AKAP4 protein sequence (Uniprot ref. Q5JQC9) which is 70% homologous between mammals. The anti-pro AKAP4 (clone 6F12) antibody epitope is 100% homologous between mammals.

Determined by its ability to recognise the prodomain of human AKAP4 protein. This monoclonal antibody (clone 6F12) only recognizes the pro-form of AKAP4 (110 kDa / 854 AA), the prodomain (21 kDa) and does not react with the AKAP4 (82 kDa / 665 AA). It reacts also with AKAP4 proteins from horse, bull, mouse, rat and ram semens.

Research Use Only Product (RUO) / Not for Diagnosis or Therapeutic Use.

Background on AKAP4 protein

Pro-AKAP4 is processed into mature AKAP4 by proteolytic cleavage of the amino-terminal prodomain (see picture).

AKAP4 (A-Kinase Anchor Protein 4) protein belongs to the family of A-kinase anchor proteins (AKAPs) all sharing a common function of binding to the regulatory subunit of protein kinase A (PKA) and confining the PKA holoenzyme to discrete locations within the cell.

The human AKAP4 gene is located on chromosome X and encodes a 854 amino acid polypeptide localized in the fibrous sheath of the sperm flagellum, AKAP4 plays a major role in sperm motility.

AKAP4 is also named AKAP-4, AKAP82 (A-Kinase Anchor Protein 82 KDa), PRKA4 (Protein Kinase A Anchoring Protein 4), HI, CT99 (Cancer/Testis Antigen 99), FSC1 (Fibrous sheath component 1) or P82.

The monoclonal antibody (clone 6F12) only recognizes the pro-form of AKAP4. It does not react with the cleaved forms AKAP4.

Western blotting and immunocytochemistry techniques using the monoclonal anti-pro AKAP4 antibody clone 6F12 showed that the pro-AKAP4 is specifically expressed in human, equine, porcine, bovine murine and ovine spermatozoa.

Mouse monoclonal antibody clone 6F12 is suitable for Western Blot, Immunofluorescence, ELISA and Immunohistochemistry (see applications).
