Summary: Enables cAMP-dependent protein kinase activity. Involved in several processes, including intracellular signal transduction; negative regulation of cytoplasmic mRNA processing body assembly; and protein import into nucleus. Located in chromatin; cytoplasm; and nucleus. Part of cAMP-dependent protein kinase complex. Human ortholog(s) of this gene implicated in platelet-type bleeding disorder 19. Orthologous to several human genes including PRKX (protein kinase X-linked). [provided by Alliance of Genome Resources, Apr 2022]
