Transcriptional Regulation of Hamster P-glycoprotein

P-glycoprotein of Chinese Hamster
P-glycoprtein gene of Chinese hamster shows a single start-site in drug-sensitive cells but multiple start-sites in drug resistant cells. What are the mechanisms underlying the transcriptional regulation of Pgp1 in diffrent cell types? Hope you will find something interesting here.
TATA-less Multiple Start-site Promoters
Pgp1 promoter belongs to a class of TATA-less promoters with multiple start-sites. This is a sub class of TATA-less promoters. Many natural promoters are TATA-less promoters.
MED-1
Dr. Tan A. Ince from Dr. Kathleen W. Scotto's Lab identified a downstream consensus sequence for TATA-less multiple start-site promoters.
