ZNF711

ZNF711 is an X-chromosomal zinc finger transcription factor that controls gene expression by partnering with histone-modifying enzymes at target promoters (PMID:20346720). Its defining biochemical partnership is a physical interaction with the histone demethylase PHF8, with which it co-occupies a subset of target promoters, including the X-linked intellectual disability gene JARID1C, linking the two proteins at transcription initiation sites (PMID:20346720). ZNF711 acts as a context-dependent regulator: it functions as an activator by recruiting the H3K9me2 demethylase JHDM2A to the SLC31A1 promoter to drive its transcription (PMID:34521054) and by binding the AR promoter to upregulate AR while forming a complex with BMI1 and AR that suppresses CpG methylation at AR and its downstream targets KLK3 and TMPRSS2 (PMID:41656388); conversely, during neutrophil maturation it acts in a DNA-binding-independent, repressive mode by sequestering PHF8 away from target promoters (PMID:41709745). ZNF711 expression is itself transcriptionally constrained by a MAFF–BATF3 complex that binds its promoter (PMID:38908812), and it participates in developmental transcriptional hierarchies, binding the Atf3 promoter and shaping mesoderm and hematopoietic lineage choice in differentiating mouse cells (PMID:41200855). Structurally, its seventh zinc finger adopts a tridentate metal-binding ββα-fold with intrinsic esterase activity toward 4-nitrophenyl acetate (PMID:39180464, PMID:38645208).
