Protein: Histone lysine acetyltransferase CREBBP (EC 2.3.1.48) (Protein lactyltransferas CREBBP) (EC 2.3.1.-) (Protein-lysine acetyltransferase CREBBP) (EC 2.3.1.-) (Q6JHU9)
Organism: Rattus norvegicus (Rat)
Function: Acetylates histones, giving a specific tag for transcriptional activation (By similarity). Also acetylates non-histone proteins, like DDX21, FBL, IRF2, MAFG, NCOA3, POLR1E/PAF53 and FOXO1 (By similarity). Binds specifically to phosphorylated CREB and enhances its transcriptional activity toward cAMP-responsive genes. Acts as a coactivator of ALX1. Acts as a circadian transcriptional coactivator which enhances the activity of the circadian transcriptional activators: NPAS2-BMAL1 and CLOCK-BMAL1 heterodimers (By similarity). Acetylates PCNA; acetylation promotes removal of chromatin-bound PCNA and its degradation during nucleotide excision repair (NER) (By similarity). Acetylates POLR1E/PAF53, leading to decreased association of RNA polymerase I with the rDNA promoter region and coding region (By similarity). Acetylates DDX21, thereby inhibiting DDX21 helicase activity (By similarity). Acetylates FBL, preventing methylation of 'Gln-105' of histone H2A (H2AQ104me) (By similarity). Functions as a transcriptional coactivator for SMAD4 in the TGF-beta signaling pathway (By similarity).
Subcellular location: Cytoplasm {ECO:0000250|UniProtKB:Q92793}. Nucleus {ECO:0000250|UniProtKB:Q92793}. Note=Recruited to nuclear bodies by SS18L1/CREST. In the presence of ALX1 relocalizes from the cytoplasm to the nucleus. Relocalizes from the nucleus to the cytoplasm following UV cell damage (By similarity). {ECO:0000250|UniProtKB:Q92793}.
