Kat2b Gene Summary [Mouse]
Enables several functions, including N-acetyltransferase activity; cyclin-dependent protein serine/threonine kinase inhibitor activity; and transcription coactivator activity. Involved in internal peptidyl-lysine acetylation and regulation of primary metabolic process. Acts upstream of or within positive regulation of gluconeogenesis and positive regulation of transcription by RNA polymerase II. Located in several cellular components, including actomyosin; kinetochore; and sarcomere. Part of ATAC complex. Is expressed in several structures, including central nervous system; early conceptus; genitourinary system; hemolymphoid system gland; and lung. Orthologous to human KAT2B (lysine acetyltransferase 2B). [provided by Alliance of Genome Resources, Jul 2025]
