Ppp2ca Gene Summary [Mouse]
Enables GABA receptor binding activity and protein serine/threonine phosphatase activity. Involved in T cell homeostasis; negative regulation of glycolytic process through fructose-6-phosphate; and regulation of intracellular signal transduction. Acts upstream of or within mesoderm development. Located in chromosome, centromeric region; cytosol; and plasma membrane. Part of protein phosphatase type 2A complex. Is active in synapse. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Orthologous to human PPP2CA (protein phosphatase 2 catalytic subunit alpha). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Ppp2ca often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
