Predicted to enable protein kinase A binding activity. Predicted to be involved in flagellated sperm motility and protein localization. Predicted to act upstream of or within establishment of protein localization; motile cilium assembly; and transmembrane receptor protein serine/threonine kinase signaling pathway. Predicted to be located in Z disc; perinuclear region of cytoplasm; and sperm flagellum. Predicted to be active in cytoplasm; sperm fibrous sheath; and sperm principal piece. Orthologous to human AKAP4 (A-kinase anchoring protein 4). [provided by Alliance of Genome Resources, Apr 2022]
