| Description: | Steroid or nuclear hormone receptors (4A nuclear receptor, NRs) constitute an important superfamily of transcription regulators that are involved in widely diverse physiological functions, including control of embryonic development, cell differentiation and homeostasis. Members of the superfamily include the steroid hormone receptors and receptors for thyroid hormone, retinoids, 1,25-dihydroxy-vitamin D3 and a variety of other ligands []. The proteins function as dimeric molecules in nuclei to regulate the transcription of target genes in a ligand-responsive manner [, ]. In addition to C-terminal ligand-binding domains, these nuclear receptors contain a highly-conserved, N-terminal zinc-finger that mediates specific binding to target DNA sequences, termed ligand-responsive elements. In the absence of ligand, steroid hormone receptors are thought to be weakly associated with nuclear components; hormone binding greatly increases receptor affinity.NRs are extremely important in medical research, a large number of them being implicated in diseases such as cancer, diabetes, hormone resistance syndromes, etc. While several NRs act as ligand-inducible transcription factors, many do not yet have a defined ligand and are accordingly termed 'orphan' receptors. During the last decade, more than 300 NRs have been described, many of which are orphans, which cannot easily be named due to current nomenclature confusions in the literature. However, a new system has recently been introduced in an attempt to rationalise the increasingly complex set of names used to describe superfamily members.NGFI-B is an early response protein and orphan member of the steroid hormone receptor superfamily []. It is expressed in the lung, brain and superior cervical ganglia, and high levels are also seen in adrenaltissue. While members of this superfamily typically bind DNA as dimers, NGFI-B binds as a monomer. A domain separate from the NGFI-B zinc fingers(the so-called A box) has been identified and is required for recognition of two adenine-thymidine base pairs at the 5' end of the NGFI-B DNA bindingelement []. | Short Name: | Nuc_orp_HMR_rcpt |
