Enables several functions, including enzyme binding activity; protein kinase A regulatory subunit binding activity; and tubulin binding activity. Involved in several processes, including cellular response to organonitrogen compound; negative regulation of protein dephosphorylation; and negative regulation of protein import into nucleus. Located in several cellular components, including lipid droplet; mitochondrial crista; and neuromuscular junction. Biomarker of brain ischemia. Orthologous to human AKAP1 (A-kinase anchoring protein 1). [provided by Alliance of Genome Resources, Apr 2022]
