In this paper we report the cloning and characterization of cDNA encoding a novel, short form of heparin-binding EGF-like growth factor (SF HB-EGF), and show expression of specific mRNA in various tissues and cell types. Our data suggest that SF HB-EGF mRNA is a product of alternative splicing. Like normal HB-EGF, SF HB-EGF contains the signal peptide, the propeptide, the heparin-binding domain and the first two conservative disulfide loops of the EGF unit. Instead of the third disulfide loop, the spacer, the transmembrane and the cytoplasmic domains, SF HB-EGF has a nine amino acid tail.
