This domain is found in a group of mostly fungal proteins, including the Polycomb repressive complex 2 (PRC2) subunit Ezh2 from Chaetomium thermophilum (Swiss:G0SDW4), which is responsible for methylation of histone H3 lysine 27 (H3K27) and therefore involved in epigenetic gene silencing. This entry represents the domain found N-terminal to to the SET domain (Pfam:PF00856). It contains a Zn3Cys8His and a Zn3Cys9 cluster [1-4].	Domain

Polycomb repressive complex 2 (PRC2) carries out the methylation of lysine 27 of histone H3, a hallmark of repressive chromatin. Three core subunits make up the catalytic core of PRC2; the SET domain containing EZH2, the zinc-finger containing SUZ12 and the WD40 repeat protein EED. The complex forms a compact arrangement of three lobes. The middle lobe largely comprises two domains that mark the beginning of the carboxy (C)-terminal region of EZH2 (MCSS and SANT2) and the helical, C-terminal, component of the Suz12 Vefs domain. This entry describes the MCSS (also known as SANT2L) domain. There is one zinc binding (Zn1Cys3His1) which is formed solely by MCSS [1, 2].	Domain
