Summary: Predicted to be a structural constituent of chromatin. Involved in negative regulation of DNA-templated transcription and negative regulation of cell fate specification. Located in chromatin; condensed chromosome; and nucleus. Is expressed in several structures, including somatic gonad. Orthologous to several human genes including H2AZ2 (H2A.Z variant histone 2).

What's a GeneRIF?

HTZ-1 and MYS-1 repress ceh-22 when UTX-1 removes its silencing mark, H3K27 methylation on the ceh-22 locus, thereby maintaining the fates of SGCs.
