Ligand Binding Domain. Nuclear hormone receptors are ligand-activated transcription factors that regulate gene expression by interacting with specific DNA sequences upstream of their target genes. The mechanism of action for these receptors involves as a first step activation through binding of the hormone and as a second step the receptor binding to DNA. Domain 1 is an ADP binding domain that may be ancient and could potentially be used in combination with other ligand binding motifs such as CoA. Keywords: RNA structure; X-ray crystallography; metal ions; nucleotide binding; riboregulation. The ligand binding domain is the cavity on the "bottom" of the receptor in the volume defined by H 3, H 5, H 12 and the "loop" (the yellow beta sheets including the cyan hairpin turn). Although the general topology of the receptor fold is common among the receptor types, there is variation in the length and composition of the helical segments and the loop region.

5 CRD2 and CRD3 form the ligand binding pocket for TNF-alpha. 5 Previous studies have shown that TNF R superfamily signaling may be induced upon ligand 2015-05-29 A Binding Site Domain is a region of protein that physically interacts stereospecifically, and usually at high affinity, with a specific ligand, substrate, or a specific domain of some complex target biomolecule, such as a protein, lipid, carbohydrate, or nucleic acid. Typically, but not necessarily, the interaction results in protein conformational alteration and functional modification.

A secreted WNT-ligand-binding domain of FZD5 generated by a frameshift mutation causes autosomal dominant coloboma Ocular coloboma is a common eye malformation resulting from incomplete fusion of the optic fissure during development. Coloboma is often associated with microphthalmia and/or contralateral anophthalmia.

Jump To: Binding Domain Ligand Binding Nuclear Receptors. The nuclear receptors constitute a super family of protein hormones that serve as transcription factors. Glucocorticoid receptor ligand binding domain (GR-LBD) is a 57.85 kDa recombinant human protein (amino acids 521-777) expressed as a glutathione-S-transferast (GST) fusion protein in baculovirus-infected insect cells. 2020-11-20 Androgen receptor ligand binding domain (AR-LBD) is a 64.42 kDa recombinant rat protein, expressed as a GST- and His-tagged protein in insect cells. The protein contains the hinge region and an LBD amino acid sequence identical to that of the human LBD. From Wikipedia, the free encyclopedia The WW domain, (also known as the rsp5-domain or WWP repeating motif) is a modular protein domain that mediates specific interactions with protein ligands.
