NHERF
Sodium-hydrogen antiporter 3 regulator 1 is a regulator of Sodium-hydrogen antiporter 3. It is encoded by the gene ''SLC9A3R1''. It is also known as ERM Binding Protein 50 (EBP50) or Na+/H+ Exchanger Regulatory Factor (NHERF1). It is believed to interact via long-range allostery, involving significant protein dynamics. Mechanism Members of the ezrin (VIL2; MIM 123900)-radixin (RDX; MIM 179410)-moesin (MSN; MIM 309845) (ERM) protein family are highly concentrated in the apical aspect of polarized epithelial cells. These cells are studded with microvilli containing bundles of actin filaments, which must attach to the membrane to assemble and maintain the microvilli. The ERM proteins, together with merlin, the NF2 (MIM 607379) gene product, are thought to be linkers between integral membrane and cytoskeletal proteins, and they bind directly to actin in vitro. Actin cytoskeleton reorganization requires the activation of a sodium/hydrogen exchanger (SLC9A3; MIM 182307). SLC9A3R1 is a ...

Neutron Spin Echo
Neutron spin echo spectroscopy is an inelastic neutron scattering technique invented by Ferenc Mezei in the 1970s, and developed in collaboration with John Hayter. In recognition of his work and in other areas, Mezei was awarded the first Walter Haelg Prize in 1999. In magnetic resonance, a spin echo is the refocusing of spin magnetisation by a pulse of resonant electromagnetic radiation. The spin echo spectrometer possesses an extremely high energy resolution (roughly one part in 100,000). Additionally, it measures the density-density correlation (or intermediate scattering function) F(Q,t) as a function of momentum transfer Q and time. Other neutron scattering techniques measure the dynamic structure factor S(Q,ω), which can be converted to F(Q,t) by a Fourier transform, which may be difficult in practice. For weak inelastic features S(Q,ω) is better suited, however, for (slow) relaxations the natural representation is given by F(Q,t). Because of its extraordina ...

Ezrin
Ezrin also known as cytovillin or villin-2 is a protein that in humans is encoded by the ''EZR'' gene. Structure The N-terminus of ezrin contains a FERM domain which is further subdivided into three subdomains. The C-terminus contain an ERM domain. Function The cytoplasmic peripheral protein encoded by this gene can be phosphorylated by protein-tyrosine kinase in microvilli and is a member of the ERM protein family. This protein serves as a linker between plasma membrane and actin cytoskeleton. It plays a key role in cell surface structure adhesion, migration, and organization. The N-terminal domain (also called FERM domain) binds sodium-hydrogen exchanger regulatory factor (NHERF) protein (involving long-range allostery). This binding can happen only when ezrin is in its active state. The activation of ezrin occurs in synergism of the two factors: 1) binding of the N-terminal domain to phosphatidylinositol(4,5)bis-phosphate (PIP2) and 2) phosphorylation of threonine T5 ...

PDGFRB
Platelet-derived growth factor receptor beta is a protein that in humans is encoded by the ''PDGFRB'' gene. Mutations in PDGFRB are mainly associated with the clonal eosinophilia class of malignancies. Gene The ''PDGFRB'' gene is located on human chromosome 5 at position q32 (designated as 5q32) and contains 25 exons. The gene is flanked by the genes for granulocyte-macrophage colony-stimulating factor and Colony stimulating factor 1 receptor (also termed macrophage-colony stimulating factor receptor), all three of which may be lost together by a single deletional mutation thereby causing development of the 5q-syndrome. Other genetic abnormalities in ''PDGFRB'' lead to various forms of potentially malignant bone marrow disorders: small deletions in and chromosome translocations causing fusions between ''PDGFRB'' and any one of at least 30 genes can cause Myeloproliferative neoplasms that commonly involve eosinophilia, eosinophil-induced organ injury, and possible progressio ...

Radixin
Radixin is a protein that in humans is encoded by the ''RDX'' gene. Radixin is a cytoskeletal protein that may be important in linking actin to the plasma membrane. It is highly similar in sequence to both ezrin and moesin. The radixin gene has been localized by fluorescence in situ hybridization to 11q23. A truncated version representing a pseudogene (RDXP2) was assigned to Xp21.3. Another pseudogene that seemed to lack introns (RDXP1) was mapped to 11p by Southern and PCR analyses. Interactions Radixin has been shown to interact with GNA13. See also * ERM protein family The ERM protein family consists of three closely related proteins, ezrin, radixin and moesin. The three paralogs, ezrin, radixin and moesin, are present in vertebrates, whereas other species have only one ERM gene. Therefore, in vertebrates these ...

Moesin
Moesin is a protein that in humans is encoded by the ''MSN'' gene. Moesin (for membrane-organizing extension spike protein) is a member of the ERM protein family which includes ezrin and radixin. ERM proteins appear to function as cross-linkers between plasma membranes and actin-based cytoskeletons. Moesin is localized to filopodia and other membranous protrusions that are important for cell–cell recognition and signaling and for cell movement. Interactions Moesin has been shown to interact with: * CD43 * ICAM3 * Neutrophil cytosolic factor 1, * Neutrophil cytosolic factor 4 * VCAM-1 Vascular cell adhesion protein 1 also known as vascular cell adhesion molecule 1 (VCAM-1) or cluster of differentiation 106 (CD106) is a protein that in humans is encoded by the ''VCAM1'' gene.

YAP1
YAP1 (yes-associated protein 1), also known as YAP or YAP65, is a protein that acts as a transcription coregulator that promotes transcription of genes involved in cellular proliferation and suppressing apoptotic genes. YAP1 is a component in the hippo signaling pathway which regulates organ size, regeneration, and tumorigenesis. YAP1 was first identified by virtue of its ability to associate with the SH3 domain of Yes and Src protein tyrosine kinases. ''YAP1'' is a potent oncogene, which is amplified in various human cancers. Structure Cloning of the YAP1 gene facilitated the identification of a modular protein domain, known as the WW domain. Two splice isoforms of the YAP1 gene product were initially identified, named YAP1-1 and YAP1-2, which differed by the presence of an extra 38 amino acids that encoded the WW domain. Apart from the WW domain, the modular structure of YAP1 contains a proline-rich region at the very amino terminus, which is followed by a TID (TEAD tran ...

Parathyroid Hormone Receptor 1
Parathyroid hormone/parathyroid hormone-related peptide receptor, also known as parathyroid hormone 1 receptor (PTH1R), is a protein that in humans is encoded by the ''PTH1R'' gene. PTH1R functions as a receptor for parathyroid hormone ( PTH) and for parathyroid hormone-related protein (PTHrP), also called parathyroid hormone-like hormone (PTHLH). Function This "classical" PTH receptor is expressed in high levels in bone and kidney and regulates calcium ion homeostasis through activation of adenylate cyclase and phospholipase C. In bone, it is expressed on the surface of osteoblasts. When the receptor is activated through PTH binding, osteoblasts express RANKL (Receptor Activator of Nuclear Factor kB Ligand), which binds to RANK (Receptor Activator of Nuclear Factor kB) on osteoclasts. This turns on osteoclasts to ultimately increase the resorption rate. Mechanism It is a member of the secretin family of G protein-coupled receptors. The activity of this receptor is mediated by ...

PDGFRA
PDGFRA, i.e. platelet-derived growth factor receptor A, also termed PDGFRα, i.e. platelet-derived growth factor receptor α, or CD140a i.e. Cluster of Differentiation 140a, is a receptor located on the surface of a wide range of cell types. This receptor binds to certain isoforms of platelet-derived growth factors (PDGFs) and thereby becomes active in stimulating cell signaling pathways that elicit responses such as cellular growth and differentiation. The receptor is critical for the development of certain tissues and organs during embryogenesis and for the maintenance of these tissues and organs, particularly hematologic tissues, throughout life. Mutations in the gene which codes for PDGFRA, i.e. the ''PDGFRA'' gene, are associated with an array of clinically significant neoplasms, notably ones of the clonal hypereosinophilia class of malignancies, as well as gastrointestinal stromal tumors (GISTs). Overall structure This gene encodes a typical receptor tyrosine kinase, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
