GATA-2: Products

GATA proteins are transcriptional coactivators with two GATA-type zinc fingers. GATAs bind to the consensus DNA sequence (A/T) GATA (A/G) to control diverse tissue-specific programs of gene expression and morphogenesis. GATA-1, -2, -3 are selectively expressed in hematopoietic and endothelial cells, while GATA-4, -5, and -6 are expressed in developing heart and gut-derived tissues. GATA-1 and -3 exist in multiple alternatively spliced isoforms.

GATA-2 is expressed in hematopoietic progenitors and stem cells. GATA-2 expression is associated with cell proliferation. GATA-2 is 480 amino acids in length and contains 2 Zn²⁺ finger domains responsible for DNA binding (aa 295 - 319 and 349 - 373). Over aa 15 - 279 human GATA-2 share 96% identity with mouse GATA-2.
