This family contains the fungal KAT11 protein (previously known as RTT109) which is required for H3K56 acetylation. Loss of KAT11 results in the loss of H3K56 acetylation, both on bulk histone and on chromatin [1]. KAT11 and H3K56 acetylation appear to correlate with actively transcribed genes and associate with the elongating form of Pol II in yeast [1]. This family also incorporates the p300/CBP histone acetyltransferase domain which has different catalytic properties and cofactor regulation to KAT11 [3].

PF06001CREB-binding protein/p300, atypical RING domain (RING_CBP-p300)CREB-binding protein/p300, atypical RING domainCBP (CREB-binding protein) and p300 (also known as CREBBP or KAT3A and EP300 or KAT3B, respectively) are two histone acetyltransferases (HATs) that associate with and acetylate transcriptional regulators and chromatin. The catalytic core of animal CB ...CBP (CREB-binding protein) and p300 (also known as CREBBP or KAT3A and EP300 or KAT3B, respectively) are two histone acetyltransferases (HATs) that associate with and acetylate transcriptional regulators and chromatin. The catalytic core of animal CBP-p300 contains a bromodomain, a CH2 region containing a discontinuous PHD domain interrupted by this RING domain, and a HAT domain. Bromodomain-RING-PHD forms a compact module in which the RING domain is juxtaposed with the HAT substrate-binding site. This RING domain contains only a single zinc ion-binding cluster instead of two; instead of a second zinc atom, a network of hydrophobic interactions stabilizes the domain. The RING domain has an inhibitory role. Disease mutations that disrupt RING attachment lead to upregulation of HAT activity. HAT regulation may require repositioning of the RING domain to facilitate access to an otherwise partially occluded HAT active site. Plant CBP-p300 type HATs lack a bromodomain whose role in the animal animal CBP-p300's is to bind acetylated histones; it has been suggested that these plant proteins may utilise a different domain or another bromodomain protein to perform this function [1]. This RING domain has also been referred to as DUF902.
