[[http://www.uniprot.org/uniprot/HAT2_SCHPO HAT2_SCHPO]] Regulatory subunit of the histone acetylase B (HAT-B) complex (By similarity). The complex acetylates 'Lys-12' of histone H4 which is required for telomeric silencing (By similarity). Component of the CENP-A recruiting complex that ensures the integrity of mitotic spindles through maintenance of kinetochore factors mis6/CENP-I and cnp1/CENP-A (PubMed:15369671, PubMed:24774534, PubMed:24789708, PubMed:25375240).

== Publication Abstract from PubMed ==
Centromeric chromatin in fission yeast is distinguished by the presence of nucleosomes containing the histone H3 variant Cnp1(CENP-A) Cell cycle-specific deposition of Cnp1 requires the Mis16-Mis18-Mis19 complex, which is thought to direct recruitment of Scm3-chaperoned Cnp1/histone H4 dimers to DNA. Here, we present the structure of the essential Mis18 partner protein Mis19 and describe its interaction with Mis16, revealing a bipartite-binding site. We provide data on the stoichiometry and overall architecture of the complex and provide detailed insights into the Mis18-Mis19 interface.
