The receptors relay the information encoded by the ligand through the activation of heterotrimeric G proteins and intracellular effector molecules. To ensure the appropriate regulation of the signalling cascade, it is vital to properly inactivate the receptor. This inactivation is achieved, in part, by the binding of a soluble protein, arrestin, which uncouples the receptor from the downstream G protein after the receptors are phosphorylated by G protein-coupled receptor kinases. In addition to the inactivation of G protein-coupled receptors, arrestins have also been implicated in the endocytosis of receptors and cross talk with other signalling pathways. Arrestin (retinal S-antigen) is a major protein of the retinal rod outer segments. It interacts with photo-activated phosphorylated rhodopsin, inhibiting or 'arresting' its ability to interact with transducin []. The protein binds calcium, and shows similarity in its C terminus to alpha-transducin and other purine nucleotide-binding proteins. In mammals, arrestin is associated with autoimmune uveitis. Arrestins comprise a family of closely-related proteins that includes beta-arrestin-1 and -2, which regulate the function of beta-adrenergic receptors by binding to their phosphorylated forms, impairing their capacity to activate G(S) proteins; Cone photoreceptors C-arrestin (arrestin-X) [], which could bind to phosphorylated red/green opsins; and Drosophila phosrestins I and II, which undergo light-induced phosphorylation, and probably play a role in photoreceptor transduction [, , ]. The crystal structure of bovine retinal arrestin comprises two domains of antiparallel beta-sheets connected through a hinge region and one short alpha-helix on the back of the amino-terminal fold []. The binding region for phosphorylated light-activated rhodopsin is located at the N-terminal domain, as indicated by the docking of the photoreceptor to the three-dimensional structure of arrestin. The N-terminal domain consists of an immunoglobulin-like beta-sandwich structure. This entry represents proteins with immunoglobulin-like domains that are similar to those found in arrestin.; PDB: 1SUJ_A 3UGX_A 1CF1_B 1AYR_A 3UGU_A 3P2D_B 1ZSH_A 2WTR_B 3GC3_A 1G4R_A ....

The receptors relay the information encoded by the ligand through the activation of heterotrimeric G proteins and intracellular effector molecules. To ensure the appropriate regulation of the signalling cascade, it is vital to properly inactivate the receptor. This inactivation is achieved, in part, by the binding of a soluble protein, arrestin, which uncouples the receptor from the downstream G protein after the receptors are phosphorylated by G protein-coupled receptor kinases. In addition to the inactivation of G protein-coupled receptors, arrestins have also been implicated in the endocytosis of receptors and cross talk with other signalling pathways. Arrestin (retinal S-antigen) is a major protein of the retinal rod outer segments. It interacts with photo-activated phosphorylated rhodopsin, inhibiting or 'arresting' its ability to interact with transducin []. The protein binds calcium, and shows similarity in its C terminus to alpha-transducin and other purine nucleotide-binding proteins. In mammals, arrestin is associated with autoimmune uveitis. Arrestins comprise a family of closely-related proteins that includes beta-arrestin-1 and -2, which regulate the function of beta-adrenergic receptors by binding to their phosphorylated forms, impairing their capacity to activate G(S) proteins; Cone photoreceptors C-arrestin (arrestin-X) [], which could bind to phosphorylated red/green opsins; and Drosophila phosrestins I and II, which undergo light-induced phosphorylation, and probably play a role in photoreceptor transduction [, , ]. The crystal structure of bovine retinal arrestin comprises two domains of antiparallel beta-sheets connected through a hinge region and one short alpha-helix on the back of the amino-terminal fold []. The binding region for phosphorylated light-activated rhodopsin is located at the N-terminal domain, as indicated by the docking of the photoreceptor to the three-dimensional structure of arrestin. The N-terminal domain consists of an immunoglobulin-like beta-sandwich structure. This entry represents proteins with immunoglobulin-like domains that are similar to those found in arrestin.; PDB: 1SUJ_A 3UGX_A 1CF1_B 1AYR_A 3UGU_A 3P2D_B 1ZSH_A 2WTR_B 3GC3_A 1G4R_A ....

The structure of the RNase P subunit, Rpp29, from Methanobacterium thermoautotrophicum has been determined. Mth Rpp29 is a member of the oligonucleotide/oligosaccharide binding fold family. It contains a structured beta-barrel core and unstructured N- and C-terminal extensions bearing several highly conserved amino acid residues that could be involved in RNA contacts in the protein-RNA complex []. Rpp29 (3.1.26.5 from EC) catalyses the endonucleolytic cleavage of RNA, removing 5'-extranucleotides from tRNA precursor. It interacts with the Rpp25 and Pop5 subunits. RNase P is a ubiquitous ribonucleoprotein enzyme primarily responsible for cleaving the 5' leader sequence during maturation of tRNAs in all three domains of life. In eubacteria, this enzyme is made up of two subunits: a large RNA (approximately 120 kDa) responsible for mediating catalysis, and a small protein cofactor (approximately 15 kDa) that modulates substrate recognition and is required for efficient in vivo catalysis. In contrast, multiple proteins are associated with eukaryotic and archaeal RNase P, and these proteins exhibit no recognizable homology to the conserved bacterial protein subunit. In reconstitution experiments with recombinantly expressed and purified protein subunits Mth Rpp29, a homologue of the Rpp29 protein subunit from eukaryotic RNase P, is an essential protein component of the archaeal holoenzyme []. In Saccharomyces cerevisiae (Baker's yeast), RNase P consists of 9 protein subunits (Pop1, Pop3-8, Rpr2 and Rpp1), while in humans there are 10 subunits (Rpp14, 20, 21, 25, 29, 30, 38, 40, hPop1, 5). RNase MRP (mitochondrial RNA processing) is an rRNA processing enzyme that cleaves a specific site within precursor rRNA to generate the mature 5'-end of 5.8S rRNA []. RNase MRP also cleaves primers for mitochondrial DNA replication and CLB2 mRNA. In yeast, RNase MRP possesses one putatively catalytic RNA and at least 9 protein subunits and is highly related to RNase P (Pop1, Pop3-Pop8, Rpp1, Snm1 and Rmp1).; GO: 0003723 RNA binding, 0004540 ribonuclease activity, 0006364 rRNA processing, 0006379 mRNA cleavage, 0008033 tRNA processing, 0000172 ribonuclease MRP complex, 0030677 ribonuclease P complex; PDB: 1V76_B 2ZAE_C 1OQK_A 2KI7_A 1TSF_A 1TS9_A 1PC0_A.
