Summary: Enables several functions, including histone H3 acetyltransferase activity; histone methyltransferase binding activity; and transcription coactivator activity. Involved in several processes, including nervous system development; regulation of canonical Wnt signaling pathway; and regulation of cell cycle process. Located in nucleus and polytene chromosome. Part of histone acetyltransferase complex and histone methyltransferase complex. Is expressed in several structures, including adult brain cell body rind; embryonic peripheral glial cell; and larval nervous system. Used to study Rubinstein-Taybi syndrome and alcohol use disorder. Human ortholog(s) of this gene implicated in Rubinstein-Taybi syndrome; acute lymphoblastic leukemia; acute myeloid leukemia; colorectal cancer; and congestive heart failure. Orthologous to human CREBBP (CREB binding protein) and EP300 (E1A binding protein p300). [provided by Alliance of Genome Resources, Dec 2024]

Trx, Ash1, and CBP proteins are required for the correct chromosome segregation and that Ash1 and CBP mediate for Cid/CENP-A recruitment at centromeres through post-translational histone modifications. Centromeric H3 histone is consistently acetylated in K27 by CBP and that nej and ash1 silencing respectively causes a decrease in H3K27 acetylation and H3K4 methylation along with an impairment of Cid loading.
