In all secreted proteins related to the epidermal growth factor (EGF), EGF domains that occur in a mature factor are each encoded by two exons, and those that do not, by one exon. During splicing, additional exon 3a can be inserted between exons 3 and 4, which code for the EGF domain of the mature heparin-binding EGF-like growth factor (HB-EGF). The(More)
A new mRNA coding for the heparin-binding EGF-like growth factor (HB-EGF) was found in Vero cells. The corresponding cDNA had C-156 in place of T, which resulted in a loss of the NheI site and replacement of Leu-33 with Pro in the HB-EGF precursor. The known and new forms of the precursor were accordingly termed L and P. A conformational change in the(More)
23 Effective therapy of intoxications caused by the Shiga toxin type 2 Stx2 has not yet been developed. The most promising approach for prevention is the preventive immunization against Stx2, and for the treatment of acute cases it is more preferable to use protective antibodies. In this study, we obtained non toxic Stx2 variants, immunization with which(More)
The effect of UV-irradiation on host and virus-specific RNA synthesis in cells infected or transformed by tumor viruses (Ad 5 and SV 40) was studied. It was found that the synthesis of host and Ad 5 RNA in infected KB cells was almost equally inhibited upon UV-irradiation; the transcription of the EcoRI produced fragments-fragment B was inhibited to a(More)
The structure of the green monkey Chlorocebus aethiops heparin-binding EGF-like growth factor (HB-EGF) gene was compared with that of the corresponding human gene. Exon 3a, characteristic of the short form of HB-EGF (SF-HB-EGF), was mapped between exons 3 and 4, approximately 700 bp away from the latter. In several human and simian cell lines, most of the(More)
