The genes for all 4 subunits of the T-cell antigen receptor (alpha, beta, gamma and delta) are controlled by distinct enhancers and their enhancer-binding proteins.
Marine and Winoto (1991) identified a common TCR regulatory element by demonstrating binding of the enhancer-binding protein GATA3 to the enhancer elements of all 4 TCR genes.
GATA3 had been shown in the chicken to be an enhancer-binding protein containing a zinc finger domain.
GATA3 mRNA was demonstrated by Northern blot analysis in T cells but not in B cells or macrophages.
GATA3 is abundantly expressed in the T-lymphocyte lineage and is thought to participate in T-cell receptor gene activation through binding to enhancers.
Labastie et al.
(1994) cloned the human gene and the 5-prime end of the mouse gene.
The human gene comprises 6 exons distributed over 17 kb of DNA.
Its 2 zinc fingers are encoded by 2 separate exons highly conserved with those of GATA1, but no other structural homologies between the 2 genes could be found.
