Enables cAMP binding activity and cAMP-dependent protein kinase regulator activity. Involved in female meiotic nuclear division; negative regulation of meiotic nuclear division; and regulation of protein kinase activity. Located in cytoplasm. Part of cAMP-dependent protein kinase complex. Human ortholog(s) of this gene implicated in Carney complex; acrodysostosis; and primary pigmented nodular adrenocortical disease. Orthologous to human PRKAR1A (protein kinase cAMP-dependent type I regulatory subunit alpha). [provided by Alliance of Genome Resources, Apr 2022]
