The function of IKZF2 (IKAROS family zinc finger 2, Ensembl gene identifier ENSG00000030419) is as follows. Transcription factor, which stabilizes the noninflammatory phenotype of regulatory T cells (Tregs) (By similarity). May possibly act via STAT5-mediated signaling (By similarity). Binds IL2 promoter and represses its transcription, possibly by epigenetic silencing, inducing deacetylation of core histones in the IL2 promoter (PubMed:37316189). In Tregs, required for FOXP3 recruitment to the IL2 promoter (By similarity). Required for outer hair cells maturation and, consequently, for hearing (By similarity). .
