GATA zinc finger

In molecular biology, GATA zinc fingers are zinc-containing domains found in a number of transcription factors (including erythroid-specific transcription factor and nitrogen regulatory proteins).

Some members of this class of zinc fingers specifically bind the DNA sequence (A/T)GATA(A/G) in the regulatory regions of genes.,[1] giving rise to the name of the domain.

[2][3] NMR studies have shown the core of the Znf to comprise 2 irregular anti-parallel beta-sheets and an alpha-helix, followed by a long loop to the C-terminal end of the finger.

It is also worth noting that many GATA-type Znfs (such as those found in the proteins GATAD2B and MTA1) have not been experimentally demonstrated to be DNA-binding domains.

For example, the N-terminal Znf of GATA1 binds specifically to a zinc finger from the transcriptional coregulator FOG1 (ZFPM1).
