MBT domain-containing protein 1 (MBTD1)

Putative Polycomb group (PcG) protein. PcG proteins maintain the transcriptionally repressive state of genes, likely via a modification of chromatin, rendering it heritably changed in its expressibility (By similarity).

Specifically binds to monomethylated and dimethylated 'Lys-20' on histone H4. .
