SMART: EGF domain annotation

EGF Epidermal growth factor-like domain.

SMART accession number:	SM00181
Description:
Interpro abstract (IPR006210):	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 (PUBMED:2372309). The repeating pattern, especially of cysteines (the so-called EGF repeat), is thought to be important to the 3D structure of the proteins, and 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, particularly in extracellular proteins.

- The structure of a Ca(2+)-binding epidermal growth factor-like domain: its role in protein-protein interactions.

- Various diverse extracellular proteins possess Ca(2+)-binding epidermal growth factor (EGF)-like domains, the function of which remains uncertain. We have determined, at high resolution (1.5 A), the crystal structure of such a domain, from human clotting factor IX, as a complex with Ca2+. The Ca2+ ligands form a classic pentagonal bipyramid with six ligands contributed by one polypeptide chain and the seventh supplied by a neighboring EGF-like domain. The crystal structure identifies the role of Ca2+ in maintaining the conformation of the N-terminal region of the domain, but more importantly demonstrates that Ca2+ can directly mediate protein-protein contacts. The observed crystal packing of the domains provides a plausible model for the association of multiple tandemly linked EGF-like domains in proteins such as fibrillin-1, Notch, and protein S. This model is consistent with the known functional data and suggests a general biological role for these domains.

- The proto-oncogene designated erbB2 or HER2 encodes a 185-kilodalton transmembrane tyrosine kinase (p185erbB2), whose overexpression has been correlated with a poor prognosis in several human malignancies. A 45-kilodalton protein heregulin-alpha (HRG-alpha) that specifically induced phosphorylation of p185erbB2 was purified from the conditioned medium of a human breast tumor cell line. Several complementary DNA clones encoding related HRGs were identified, all of which are similar to proteins in the epidermal growth factor family. Scatchard analysis of the binding of recombinant HRG to a breast tumor cell line expressing p185erbB2 showed a single high affinity binding site [dissociation constant (Kd) = 105 +/- 15 picomolar]. Heregulin transcripts were identified in several normal tissues and cancer cell lines. The HRGs may represent the natural ligands for p185erbB2.

- FEBS Lett. 1989; 251: 1-7
- Display abstract
- Multidomain proteins of the extracellular matrix (ECM) play an important role in development and maintenance of cellular organization and in tissue repair. Several ECM proteins such as laminin, tenascin and thrombospondin contain domains with homology to epidermal growth factor (EGF) and exhibit growth promoting activity. The mitogenic activity of laminin is restricted to a fragment which consists of about 25 repeating domains with partial homology to EGF and comprises the rod-like inner regions of the three short arms of the four armed molecule. The mitogenic activity does not correlate with promotion of cell attachment and neurite outgrowth for which major functional sites have been found in other regions of the laminin molecule. It is suggested that EGF-like domains in laminin, in other ECM proteins and in the extracellular portions of some membrane proteins are signals for cellular growth and differentiation. Because they are integral parts of large molecules and often of supramolecular assemblies these domains are well suited to stimulate neighboring cells in a specific and vectorial way. This concept of localized growth or differentiation signals offers an attractive mechanism for the regulation of cellular development.

- The cDNA sequence of the precursor of mouse epidermal growth factor (EGFP) has recently been reported by two groups, both of whom noted the presence of repeated similar segments, each about 40 residues long. One of these repeat units overlaps with the sequence of epidermal growth factor itself. The sequence of epidermal growth factor has been reported to be similar to that of pancreatic secretory trypsin inhibitor (PSTI) and a somewhat better match has been found with part of the sequence of bovine factor X, one of the blood coagulating factors. We report here that there is an even stronger similarity between the sequences of some of the repeat units of epidermal growth factor precursor and certain segments in factor X. This sequence similarity is also apparent in comparisons with other blood coagulation factors. On the basis of these sequence comparisons we suggest a scheme for the evolution of the epidermal growth factor precursor. We have also identified certain structural features in the precursor sequence that bear on the way in which the mature epidermal growth factor is generated.
