Domain Architecture (Details)
InterPro domains unassigned to SynO:
A sequence of about thirty to forty amino-acid residues long found in the sequence of epidermal growth factor (EGF)has been shown to be present.n a moreor less conserved form.n a large number of other.ostly animal proteins. The list of proteins currently known tocontain one or more copies of an EGF-like pattern is large and varied. The functional significance of EGF domains inwhat appear to be unrelated proteins is not yet clear. However. common feature is that these repeats are found inthe extracellular domain of membrane-bound proteins or in proteins known to be secreted (exception: prostaglandinG/H synthase). The EGF domain includes six cysteine residues which have been shown (in EGF) to be involved in disulphidebonds. The main structure is a two-stranded beta-sheet followed by a loop to a C-terminal short two-stranded sheet.Subdomains between the conserved cysteines vary in length.This entry contains EGF domains found in a variety of extracellular and membrane proteins
  IPR013111:EGF, extracellular
Laminins are the major noncollagenous components of basement membranesthat mediate cell adhesion.rowth migration.nd differentiation. They arecomposed of distinct but related alpha.eta and gamma chains. The threechains form a cross-shaped molecule that consist of a long arm and three shortglobular arms. The long arm consist of a coiled coil structure contributed byall three chains and cross-linked by interchain disulphide bonds.Beside different types of globular domains each subunit contains.n its firsthalf.onsecutive repeats of about 60 amino acids in length that include eightconserved cysteines . The tertiary structure .f this domain isremotely similar in its N-terminal to that of the EGF-like module (see ). It is known as a LE or laminin-type EGF-like domain. Thenumber of copies of the LE domain in the different forms of laminins is highlyvariable; from 3 up to 22 copies have been found.A schematic representation of the topology of the four disulphide bonds inthe LE domain is shown below.In mouse laminin gamma-1 chain.he seventh LE domain has been shown to be theonly one that binds with a high affinity to nidogen . The binding-sites arelocated on the surface within the loops C1-C3 and C5-C6 . Longconsecutive arrays of LE domains in laminins form rod-like elements of limitedflexibility .hich determine the spacing in the formation of lamininnetworks of basement membranes .
  IPR002049:EGF-like, laminin
The growth factor receptor domain is a cysteine-rich region that is found in a variety of eukaryotic proteins that are involved in the mechanism of signal transduction by receptor tyrosine kinases. Proteins containing the growth factor receptor domain include the insulin-like growth factor-binding proteins (IGFBP) .he type-1 insulin-like growth-factor receptor (IGF-1R) .nd the receptor protein-tyrosine kinase Erbb-3 (ErbB3) . The general structure of the growth factor receptor domain is a disulphide-bound fold containing a beta-hairpin with two adjacent disulphides. IGFBPs control the distribution.unction and activity of insulin-like growth factors (IGFs) IGF-I and IGF-II.hich are key regulators of cell proliferation.ifferentiation and transformation. All IGFBPs share a common domain the highest conservation is found in the N-terminal Cys-rich IGF-binding domain. The N-terminal domain contains 10-12 conserved cysteine residues. IGF-1R is a member of the tyrosine-kinase receptor superfamily that is involved in both normal growth and development and malignant transformation. The Cys-rich domain is flanked by two L-domains.nd together they contribute to hormone binding and ligand specificity.ven though they do not bind ligand directly. The Cys-rich region is composed of eight disulphide-bonded modules.even of which form a rod-shaped domain. ErbB3 is a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. The extracellular region of ErbB3 is made up of two Cys-rich domains and two L-domains.rranged alternately. The two L-domains and the first Cys-rich domain are structurally homologous to those found in IGF-1R. The two Cys-rich domains are extended repeats of seven small disulphide-containing modules. A beta-hairpin loop extends from the first Cys-rich domain to contact the C-terminal portion of the second Cys-rich domain.reating a large pore structure. The SSF signature in this entry is currently under review. Please be aware that some of the protein hits may be false positives.
  IPR009030:Growth factor, receptor
Epidermal growth factors and transforming growth factors belong to a general class of proteins that share a repeat pattern involving a number of conserved Cys residues. Growth factors are involved in cell recognition and division . The repeating pattern.specially of cysteines (the so-called EGF repeat).s thought to be important to the 3D structure of the proteins.nd hence its recognition by receptors and other molecules. The type 1 EGF signature includes six conserved cysteines believed to be involved in disulphide bond formation. The EGF motif is found frequently in nature.articularly in extracellular proteins.
