Data class	Domain;
Predictors	PROSITE; PS51810; ZF_CCHC_FOG
Name	Zinc finger CCHC FOG-type
Function	Transcriptional cofactors of the Friend of GATA (FOG) family contain either eight or nine ZnFs that are related to the classical CCHH ZnFs (which have a conserved C-X(2,5)-C-X(12)-H-X(2,5)-H sequence). Several of the fingers in each FOG protein, however, have an altered consensus sequence in which the final zinc binding histidine is replaced with a cysteine. Interestingly, it is only these variant CCHC ZbFs that mediate interactions with GATA N-terminal zinc fingers (NFs).
Scope(s)	Eukaryota Metazoa
Example(s)	Q9VPQ6 (USH_DROME);
