Enables several functions, including G-protein alpha-subunit binding activity; microtubule binding activity; and protein serine/threonine phosphatase activity. Involved in several processes, including histone dephosphorylation; positive regulation of glucocorticoid receptor signaling pathway; and response to arachidonic acid. Located in several cellular components, including cytosol; perikaryon; and proximal dendrite. Orthologous to human PPP5C (protein phosphatase 5 catalytic subunit).
