'''DNA-BINDING MECHANISM OF THE MONOMERIC ORPHAN NUCLEAR RECEPTOR NGFI-B'''<br />


==Overview==
==DNA-BINDING MECHANISM OF THE MONOMERIC ORPHAN NUCLEAR RECEPTOR NGFI-B==
The 2.7 A X-ray crystal structure of the DNA-binding domain (DBD) of the, orphan nuclear receptor, nerve growth factor-induced-B (NGFI-B), complexed, to its high-affinity DNA target, represents the first structure analysis, of a nuclear receptor DBD bound as a monomer to DNA. The structure of the, core DBD and its interactions with the major groove of the DNA are similar, to previously crystallographically solved DBD-DNA complexes in this, superfamily; however, residues C-terminal to this core form a separate and, unique substructure that interacts extensively and in a sequence-specific, way with the minor groove of its DNA target, in particular with the, characteristic 3 A-T base-pair identity element that extends 5' to the, usual nuclear receptor half-site (AGGTCA).

== Function ==
[https://www.uniprot.org/uniprot/NR4A1_RAT NR4A1_RAT] Orphan nuclear receptor. May act concomitantly with NURR1 in regulating the expression of delayed-early genes during liver regeneration. Binds the NGFI-B response element (NBRE) 5'-AAAAGGTCA-3'. May inhibit NF-kappa-B transactivation of IL2 (By similarity).
