Summary: Enables several functions, including N-acetyltransferase activity; cyclin-dependent protein serine/threonine kinase inhibitor activity; and transcription coactivator activity. Involved in several processes, including internal peptidyl-lysine acetylation; negative regulation of cyclin-dependent protein serine/threonine kinase activity; and positive regulation of nucleobase-containing compound 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, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
