Summary: Enables cAMP-dependent protein kinase activity. Involved in several processes, including intracellular signal transduction; negative regulation of cytoplasmic mRNA processing body assembly; and negative regulation of cytoplasmic translation. Located in P-body; cytoplasmic stress granule; and nucleus. Part of cAMP-dependent protein kinase complex. Human ortholog(s) of this gene implicated in adrenal cortical adenoma; congestive heart failure; fibrolamellar carcinoma; platelet-type bleeding disorder 19; and primary pigmented nodular adrenocortical disease 4. Orthologous to several human genes including PRKACA (protein kinase cAMP-activated catalytic subunit alpha); PRKACB (protein kinase cAMP-activated catalytic subunit beta); and PRKACG (protein kinase cAMP-activated catalytic subunit gamma).
