YEATS domain proteins: a diverse family with many links to chromatin modification and transcription

Chromatin modifications play crucial roles in various biological processes, An increasing number of conserved protein domains, often found in multisubunit protein complexes, are involved in establishing and recognizing different chromatin modifications. The YEATS domain is one of these domains, and its role in chromatin modifications and transcription is just beginning to be appreciated. The YEATS domain family of proteins, conserved from yeast to human, contains over 100 members in more than 70 eukaryotic species. Yaf9, Taf14, and Sas5 Lire the only YEATS domain proteins in Saccharomyces cerevisiae. Human YEATS domain family members, such as GAS41, ENL, and AF9, have a strong link to cancer. GAS41 is amplified in glioblastomas and astrocytoma; ENL and AF9 are among the most frequent translocation partners of the mixed lineage leukemia (MLL) gene. This review will focus on the best characterized YEATS proteins, discuss their diverse roles, and reflect potential functions of the YEATS domain.
