This entry includes PHF20 and PHF20L1 proteins.PHD finger protein 20 (PHF20) binds dimethyl lysine residues via its Tudor domain []. It is a component of the MLL1, MOF histone acetyltransferase []and NSL protein complexes [].PHF20L1 binds to monomethylated lysine 142 on DNA (cytosine-5) methyltransferase 1 (DNMT1). It has been shown to antagonize DNMT1 proteasomal degradation [].
This entry represents an agenet domain found in EMSY-like (AtEML) proteins, which have possible roles in chromatin regulation and are related to the BRCA2-interacting human oncoprotein EMSY []. Proteins containing this domain also include MRG2 (AT1G02740) from Arabidopsis and PHD finger protein 20-like protein 1 (PHF20L1) from animals. MRG2 binds to the FLOWERING LOCUS T locus and elevates the expression in an H3K36me3-dependent manner []. The function of PHF20L1 is not clear.
PHD finger protein 20 (PHF20) is a Methyllysine-binding protein, component of the MOF histone acetyltransferase protein complex. It consists of tandem Tudor domains at the N-terminal, an AT hook, a C2H2-type zinc finger, and a plant homeodomain (PHD) finger [, , ]. PHF20L1 binds to monomethylated lysine 142 on DNA (cytosine-5) methyltransferase 1 (DNMT1). It has been shown to antagonize DNMT1 proteasomal degradation [].This is the AT-hook domain found in PHD finger protein 20 (PHF20) and PHD finger protein 20-like (PHF20L) [, , ].
