Summary: Enables AMP-activated protein kinase activity and guanyl-nucleotide exchange factor activity. Involved in several processes, including invasive growth in response to glucose limitation; positive regulation of filamentous growth of a population of unicellular organisms; and regulation of carbohydrate biosynthetic process. Located in cellular bud neck septin ring; nuclear envelope lumen; and vacuolar membrane. Part of nucleotide-activated protein kinase complex. Human ortholog(s) of this gene implicated in Huntington's disease; breast cancer; colon cancer; and type 2 diabetes mellitus. Orthologous to human PRKAA1 (protein kinase AMP-activated catalytic subunit alpha 1) and PRKAA2 (protein kinase AMP-activated catalytic subunit alpha 2).
