Identification and Characterization of Mouse Type II Platelet-Derived Growth Factor Receptor α Transcript

抄録

Recently, we identified a novel human platelet-derived growth factor (PDGF) receptor α mRNA (type II) that differs from the known human PDGF receptor α mRNA (type I) only in its 5′-untranslated region and is regulated by E2F-1. In this study, we determined the nucleotide sequence of the mouse type II PDGF receptor α mRNA and found that the expression of this transcript was regulated by E2F-1 through an E2F-1-responsive sequence located +711/+718 downstream of the transcription start site of the type I transcript. Furthermore, we observed embryo-predominant expression of the type II transcript.
