The GATA type (IPR000679) contains the zinc finger (Znf). Several transcription factors, including erythroid-specific transcription factors and nitrogen regulatory proteins, specifically bind the DNA sequence (A/T)GATA(A/G) in the regulatory regions of genes. Therefore, we refer to them as GATA-binding transcription factors. GATA transcription factors contain two zinc fingers. Nevertheless, the domain is present in only one copy of a number of proteins.
