| Short Name | KMT2A_ePHD |
| description | The extended plant homeodomain (ePHD) zinc finger is characterized as Cys2HisCys5HisCys2His. This entry represents the ePHD finger of Histone-lysine N-methyltransferase 2A (KMT2A), which is a histone methyltransferase that belongs to the MLL subfamily of H3K4-specific histone lysine methyltransferases (KMT2). It regulates chromatin-mediated transcription through the catalysis of methylation of histone 3 lysine 4 (H3K4), and is frequently rearranged in acute leukemia []. KMT2A functions as the catalytic subunit in the MLL1 complex, which also contains WDR5, RbBP5, ASH2L and DPY30 as integral core subunits required for the efficient methylation activity of the complex [, ]. The MLL1 complex is highly active and specific for H3K4 methylation. KMT2A contains a CxxC (x for any residue) zinc finger domain, three PHD fingers, a Bromodomain domain, this extended PHD finger, two FY (phenylalanine tyrosine)-rich domains, and a SET (Suppressor of variegation, Enhancer of zeste, Trithorax) domain []. |
