Protein Domain
Type: Domain
Description: P2X purinoceptors are cell membrane ion channels, gated by adenosine 5'-triphosphate (ATP) and other nucleotides; they have been found to be widely expressed on mammalian cells, and, by means of their functional properties, can be differentiated into three sub-groups. The first group is almost equally well activated by ATP and its analogue alpha,betamethylene-ATP, whereas, the second group is not activated by the latter compound. A third type of receptor (also called P2Z) is distinguished by the fact that repeated or prolonged agonist application leads to the opening of much larger pores, allowing large molecules to traverse the cell membrane. This increased permeability rapidly leads to cell death, and lysis.Molecular cloning studies have identified seven P2X receptor subtypes, designated P2XR1-P2XR7, however, P2X1R, P2X2R, P2X3R, P2X4R, and P2X7R are functional []. These receptors are proteins that share 35-48% amino acid identity, and possess two putative transmembrane (TM) domains, separated by a long (~270 residues) intervening sequence, which is thought to form an extracellular loop. Around 1/4 of the residues within the loop are invariant between the cloned subtypes, including 10 characteristic cysteines.Studies of the functional properties of heterologously expressed P2X receptors, together with the examination of their distribution in native tissues, suggests they likely occur as both homo- and hetero multimers in vivo [, ]. Stimulation of these receptors induces changes in intracellular ion homeostasis leading to multiple key responses crucial for initiation, propagation, and resolution of inflammation []. The P2X7 subtype has an important role in the activation of lymphocyte, granulocyte, macrophage and dendritic cell responses and, therefor, it may be a promising target for anti-inflammatory therapies.This entry represents the intracellular domain found at the C-terminal domain of P2X7 (also known as P2Z receptor). P2X7 receptor has different functional properties from those of P2X1-P2X6. Key properties of the current produced are little rectification or desensitisation, and strong potentiation of responses when the concentration of extracellular Ca2 and/or Mg2 are reduced. It is also found to be relatively insensitive to ATP. In certain studies, prolonged activation of expressed P2X7 receptors causes cell permeabilization, and lysis. This domain is critical for the receptor to initiate apoptosis and not undergo desensitization. It shows a globular structure and is shaped like a wedge with three β-strands forming an antiparallel β-sheet followed by eight α-helices separated by loops that form a helical bundle [].

Description: This entry represents Pentaxins and its related proteins such as CRP (C-reactive protein) and SAP (serum amyloid P component protein) []. This entry also includes adhesion G-protein coupled receptors D2 and G6 from humans.Pentraxins (or pentaxins) [, ]are a family of proteins which show, under electron microscopy, a discoid arrangement of five noncovalently bound subunits. Proteins of the pentraxin family are involved in acute immunological responses []. Three of the principal members of the pentraxin family are serum proteins and Ca2 dependent: namely, C-reactive protein (CRP) [], serum amyloid P component protein (SAP) [], and female protein (FP) []. CRP binds to ligands containing phosphocholine, SAP binds to amyloid fibrils, DNA, chromatin, fibronectin, C4-binding proteins and glycosaminoglycans.CRP is expressed during acute phase response to tissue injury or inflammation in mammals. The protein resembles antibody and performs several functions associated with host defence: it promotes agglutination, bacterial capsular swelling and phagocytosis, and activates the classical complement pathway through its calcium-dependent binding to phosphocholine. CRPs have also been sequenced in an invertebrate, Limulus polyphemus (Atlantic horseshoe crab), where they are a normal constituent of the hemolymph [].SAP is a vertebrate protein that is a precursor of amyloid component P. It is found in all types of amyloid deposits, in glomerular basement menbrane and in elastic fibres in blood vessels. SAP binds to various lipoprotein ligands in a calcium-dependent manner, and it has been suggested that, in mammals, this may have important implications in atherosclerosis and amyloidosis [].FP is a SAP homologue found in Mesocricetus auratus (golden hamster). The concentration of this plasma protein is altered by sex steroids and stimuli that elicit an acute phase response."Long"pentraxins have N-terminal extensions to the common pentraxin domain []; one group, the neuronal pentraxins, may be involved in synapse formation and remodeling, and they may also be able to form heteromultimers []. Pentraxin proteins expressed in the nervous system are neural pentraxin I (NPI) and II (NPII) []. NPI and NPII are homologous and can exist within one species. It is suggested that both proteins mediate the uptake of synaptic macromolecules and play a role in synaptic plasticity. Apexin, a sperm acrosomal protein, is a homologue of NPII found in Cavia porcellus (Guinea pig) [].PTX3 is a long pentraxin that provides defence against infectious agents and plays several functions in tissue repair and regulation of cancer-related inflammation [].
