Product Specific Information

Western blot analysis of PA1-101 detects a prominent ~50 kDa protein in GATA3-expressing SH-SY5Y cells. The signal is enhanced in nuclear extracts due to enrichment of GATA3.
This antibody has also been validated for Immunofluorescence and IHC (P).
PA1-101 was successfully used in western blotting analysis of GATA3 in breast cancer cell lines.

Target Information

The genes for all four 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 four TCR genes.
GATA3, containing a zinc finger domain, acts as an enhancer-binding protein and is abundantly expressed in the T-lymphocyte lineage. It participates in T-cell receptor gene activation through binding to enhancers.
Labastie et al. (1994) cloned the human gene and the 5′ end of the mouse gene. The human gene comprises six exons distributed over 17 kb of DNA. Its two zinc fingers are encoded by two separate exons highly conserved with those of GATA1, though no other structural homologies between the two genes were found.
