Akap4 Gene Summary [Rat]
Predicted to enable protein kinase A binding activity. Predicted to be involved in flagellated sperm motility; protein localization; and spermatogenesis. Predicted to act upstream of or within several processes, including cell surface receptor protein serine/threonine kinase signaling pathway; establishment of protein localization; and sperm flagellum assembly. Predicted to be located in several cellular components, including Z disc; sperm flagellum; and sperm head-tail coupling apparatus. 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 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Akap4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
