Transcription factor required for development of the vascular component of the pronephric kidney, the glomus; may repress tubule-specific gene expression in the portion of the pronephros fated to form the glomus (PubMed:16818449). Recognizes and binds to the DNA sequence 5'-GCG(T/G)GGGCG-3' (By similarity). Inhibits Wnt-signaling during embryonic development (By similarity). Shuttles between nucleus and cytoplasm. Expressed in the pronephric anlage from stage 23 to 30. Also expressed in the adult kidney (mesonephros) and in testis. Binds to DNA motifs with the sequence 5'-GCG(T/G)GGGCG-3' via its C2H2-type zinc fingers. Starting from the N-terminus, the second zinc finger binds to the 3'-GCG motif, the middle zinc finger interacts with the central TGG motif, and the C-terminal zinc finger binds to the 5'-GCG motif. Binds double-stranded target DNA, irrespective of the cytosine methylation status. Has reduced affinity for target DNA where the cytosines have been oxidized to 5-hydroxymethylcytosine, 5-formylcytosine or 5-carboxylcytosine. The 9aaTAD motif is a transactivation domain present in a large number of yeast and animal transcription factors. Belongs to the EGR C2H2-type zinc-finger protein family.
