Name  Zinc finger, nuclear hormone receptor-type Short Name  Znf_hrmn_rcpt
Type  Domain Description  Steroid or nuclear hormone receptors constitute an important superfamily of transcription regulators that are involved in widely diverse physiological functions, including control of embryonic development, cell differentiation and homeostasis. The receptors function as dimeric molecules in nuclei to regulate the transcription of target genes in a ligand-responsive manner. Nuclear hormone receptors consist of a highly conserved DNA-binding domain that recognises specific sequences, connected via a linker region to a C-terminal ligand-binding domain (). In addition, certain nuclear hormone receptors have an N-terminal modulatory domain (). The DNA-binding domain can elicit either an activating or repressing effect by binding to specific regions of the DNA known as hormone-response elements [, ]. These response elements position the receptors, and the complexes recruited by them, close to the genes of which transcription is affected. The DNA-binding domains of nuclear receptors consist of two zinc-nucleated modules and a C-terminal extension, where residues in the first zinc module determine the specificity of the DNA recognition and residues in the second zinc module are involved in dimerisation. The DNA-binding domain is furthermore involved in several other functions including nuclear localisation, and interaction with transcription factors and co-activators [].Zinc finger (Znf) domains are relatively small protein motifs which contain multiple finger-like protrusions that make tandem contacts with their target molecule. Some of these domains bind zinc, but many do not; instead binding other metals such as iron, or no metal at all. For example, some family members form salt bridges to stabilise the finger-like folds. They were first identified as a DNA-binding motif in transcription factor TFIIIA from Xenopus laevis(African clawed frog), however they are now recognised to bind DNA, RNA, protein and/or lipid substrates [, , , , ]. Their binding properties depend on the amino acid sequence of the finger domains and of the linker between fingers, as well as on the higher-order structures and the number of fingers. Znf domains are often found in clusters, where fingers can have different binding specificities. There are many superfamilies of Znf motifs, varying in both sequence and structure. They display considerable versatility in binding modes, even between members of the same class (e.g. some bind DNA, others protein), suggesting that Znf motifs are stable scaffolds that have evolved specialised functions. For example, Znf-containing proteins function in gene transcription, translation, mRNA trafficking, cytoskeleton organisation, epithelial development, cell adhesion, protein folding, chromatin remodelling and zinc sensing, to name but a few []. Zinc-binding motifs are stable structures, and they rarely undergo conformational changes upon binding their target. This entry represents the two C4-type zinc finger modules involved in DNA-binding.
