PHF8(PHD finger protein 8) is a Fe2+ and 2-oxoglutarate dependent histone lysine demethylase and belongs to a family of JmjC domain-containing proteins.PHF8 also contains a plant homeodomain(PHD) finger motif in its N-terminus,which involves in transcriptional regulation.PHF8 can demethylate H3K9me2/1,H4K20me1 and H3K27me2 with JmjC domain,and also act as a transcriptional coactivator through binding to H3K4me3 via PHD finger.PHF8 regulates expression of rRNA and many protein-coding genes involved in neural...
