Alternative promoter usage is typically associated with mRNAs with differing first exons that contain or consist entirely of a 5′ untranslated region. murine testis. Using analysis we identified a putative steroidogenic factor-1 (SF-1) response element that was unique to the Bcrp1 E1U alternative promoter. Overexpression of SF-1 in murine TM4 Sertoli cells enhanced E1U mRNA… Continue reading Alternative promoter usage is typically associated with mRNAs with differing first
