description | DNA-binding domain of Retinoid-related orphan receptors (RORs) is composed of two C4-type zinc fingers. Each zinc finger contains a group of four Cys residues which coordinates a single zinc atom. ROR interacts with specific DNA sites upstream of the target gene and modulates the rate of transcriptional initiation. RORs bind as monomers to specific ROR response elements (ROREs) consisting of the consensus core motif AGGTCA preceded by a 5-bp A/T-rich sequence [].RORs are orphan NRs (steroid or nuclear hormone receptors) related to retinoic acid receptors and include ROR-alpha, ROR-beta and ROR-gamma, which are also referred to as RORA, RORB and RORC. ROR-alpha, ROR-beta and ROR-gamma regulate circadian rhythms with ROR-alpha playing the central role []. ROR-alpha has a key role in the development of the cerebellum. ROR-beta is necessary for the proliferation and differentiation of retinal cells. ROR-gamma is required for lymph-node organogenesis []. Like other members of the nuclear receptor (NR) superfamily of ligand-activated transcription factors, retinoid-related orphan receptors have a central well conserved DNA binding domain (DBD), a variable N-terminal domain, a non-conserved hinge and a C-terminal ligand binding domain. |
