Enables protein kinase A regulatory subunit binding activity. Acts upstream of or within cortical actin cytoskeleton organization; protein localization to endosome; and renal water homeostasis. Predicted to be located in several cellular components, including cytosol; nucleolus; and peroxisome. Predicted to be part of protein-containing complex. Is expressed in several structures, including alimentary system; eye; genitourinary system; immune system; and nervous system. Orthologous to human AKAP11 (A-kinase anchoring protein 11).
