Enables protein kinase A binding activity. Involved in flagellated sperm motility. Acts upstream of or within several processes, including cell surface receptor protein serine/threonine kinase signaling pathway; establishment of protein localization; and sperm flagellum assembly. Located in Z disc; perinuclear region of cytoplasm; and sperm flagellum. Orthologous to human AKAP4 (A-kinase anchoring protein 4).
