TSC22D3 polyclonal antibody

Q99576

Glucocorticoid-induced leucine zipper (GILZ) is a leucine zipper protein ex-pressed in normal lymphocytes from thymus, spleen and lymph nodes. It is absent in nonlymphoid tissues including brain, liver and kidney. GILZ mediates the immunosuppressive effects of glucocorticoid hormones, its expression is induced in T cells by dexamethasone. GILZ protects T cells from an anti-CD3 antibody-induced apoptosis by inhibiting Fas and Fas ligand expression. It interferes with Egr-2, Egr-3, NFAT/AP-1-inducible transcription factors and AP-1. The interaction of GILZ with c-Fos and c-Jun inhibits the binding of active AP-1 to its DNA consensus site in vitro. GILZ also binds NFkB subunits and inhibits the NFkB nuclear translocation. It inhibits T cell receptor-induced interleukin-2/interleukin-2 receptor expression. The binding of GILZ to Raf-1 prevents Raf-MEK-ERK activation in the MAPK pathway. GILZ is expressed by normal macrophages in nonlymphoid tissues and by tumor-infiltrating macrophages in Burkitt lymphomas. The gene encoding human GILZ maps to chromosome Xq22.3.

The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE).
