CENP-T is a family of vertebral kinetochore proteins that associates directly with CENP-W. The N-terminus of CENP-T proteins interacts directly with the Ndc80 complex in the outer kinetochore. Importantly, the CENP-T-W complex does not directly associate with CENP-A, but with histone H3 in the centromere region. CENP-T and -W form a hetero-tetramer with CENP-S and -X and bind to a ~100 bp region of nucleosome-free DNA forming a nucleosome-like structure. The DNA-CENP-T-W-S-X complex is likely to be associated with histone H3-containing nucleosomes rather than with CENP-nucleosomes. This domain is the C-terminal histone fold domain of CENP-T, which associates with chromatin [2-3].	Domain

This entry represents a histone acetyltransferase catalytic domain found in fungal proteins, including RTT109 (also known as KAT11) from budding and fission yeasts and Candida species. This domain catalyses the acetylation of lysine residues on histone H3, including H3K56, H3K9, H3K14, H3K23 and H3K27 [1,2]. The domain functions within a complex with histone chaperones such as VPS75 that regulate substrate specificity [3]. Acetylation of H3K56 by this domain promotes nucleosome assembly, DNA repair and transcriptional regulation during S-phase [1,2]. The domain is also found in other histone acetyltransferases including p300/CBP which share a similar fold but differ in catalytic properties and cofactor requirements [3]. Members of this family show conservation across most eukaryotic fungi.	Domain
