Anti-A Kinase Anchor Protein 4 antibodies are used in antigen-specific immunodetection in biological samples. The target A Kinase Anchor Protein 4 is a known alias name of the protein A-kinase anchoring protein 4, encoded by the AKAP4 gene in humans. This 854-amino acid residue protein is known to be involved in cellular localization and protein localization, among other biological processes. It is localized to the cell projections of the cell. It is reported to be expressed in the testis. Other synonyms for A Kinase Anchor Protein 4 include AKAP 82, AKAP82, and CT99.
