About PHF8

Cytogenetic location: Xp11.22 Genomic coordinates (GRCh38): X:53,936,680-54,048,936 (from NCBI)

This gene has 22 transcripts (splice variants), 206 orthologues, 4 paralogues and is associated with 3 phenotypes. Broad expression in testis (RPKM 19.3), ovary (RPKM 6.7) and 25 other tissues.

Summary

The protein encoded by this gene is a histone lysine demethylase that preferentially acts on histones in the monomethyl or dimethyl states. The encoded protein requires Fe(2+) ion, 2-oxoglutarate, and oxygen for its catalytic activity. The protein has an N-terminal PHD finger and a central Jumonji C domain. This gene is thought to function as a transcription activator. Defects in this gene are a cause of syndromic X-linked Siderius type intellectual disability (MRXSSD) and over-expression of this gene is associated with several forms of Cancer. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2017]
