Protein: PR domain zinc finger protein 8 (EC 2.1.1.-) (PR domain-containing protein 8) (Q9NQV8)
Organism: Homo sapiens (Human)
Function: Probable histone methyltransferase, preferentially acting on 'Lys-9' of histone H3 (By similarity). Involved in the control of steroidogenesis through transcriptional repression of steroidogenesis marker genes such as CYP17A1 and LHCGR (By similarity). Forms with BHLHE22 a transcriptional repressor complex controlling genes involved in neural development and neuronal differentiation (By similarity). In the retina, it is required for rod bipolar and type 2 OFF-cone bipolar cell survival (By similarity).
Subcellular location: Nucleus {ECO:0000269|PubMed:22961547}.
