Abstract

Crystal structure of a truncated epidermal growth factor receptor extracellular domain bound to transforming growth factor alpha.

Cell, 2002; PubMed, Homo sapiens TGFA — Homo sapiens EGFR

ABSTRACT: We report the crystal structure, at 2.5 A resolution, of a truncated human EGFR ectodomain bound to TGFalpha. TGFalpha interacts with both L1 and L2 domains of EGFR, making many main chain contacts with L1 and interacting with L2 via key conserved residues. The results indicate how EGFR family members can bind a family of highly variable ligands. In the 2:2 TGFalpha:sEGFR501 complex, each ligand interacts with only one receptor molecule. There are two types of dimers in the asymmetric unit: a head-to-head dimer involving contacts between the L1 and L2 domains and a back-to-back dimer dominated by interactions between the CR1 domains of each receptor. Based on sequence conservation, buried surface area, and mutagenesis experiments, the back-to-back dimer is favored to be biologically relevant.

Biologically active precursor for transforming growth factor type alpha, released by retrovirally transformed cells.

ABSTRACT: Retrovirus-transformed rat cells that actively express transforming growth factor type alpha (TGF-alpha) release into the medium a soluble protein of 17-19 kDa that has been identified as a precursor for TGF-alpha. The identification of this protein as a TGF-alpha precursor is based on its recognition by specific antibodies and by the ability of elastase to convert this protein into a 6-kDa polypeptide with the properties of mature TGF-alpha. This TGF-alpha precursor binds to epidermal growth factor/TGF-alpha receptors and activates the receptor-associated tyrosine kinase activity in intact cells. The biological potency of this precursor is not markedly increased by conversion into mature TGF-alpha in vitro. These studies demonstrate the ability of transformed cells to release a TGF-alpha precursor capable of strong mitogenic action in vivo.
