Texts: 1. You are studying a hypothetical gene, Oxy1, encoding a protein that stimulates blood-vessel growth in response to hypoxia (low oxygen). To explore how Oxy1 is regulated, you characterize how the levels of Oxy1 mRNA and protein change in response to oxygen. The results looked like this: O2 Hi Northern blots: Oxy1 probe Immunoblots: probed with antibody to Oxy1 Does oxygen regulate Oxy1 expression at the level of transcription or translation? Explain. ii) To pinpoint the cis-acting sequences that mediate this regulation, you decide to use a GFP reporter gene. You generate DNA constructs in which GFP replaces the protein-coding region of the Oxy1 gene (assume there are no introns in this gene), and introduce these into cultured cells. You then image the amount of GFP fluorescence after cells are incubated under either normal (Hi) or low (Lo) oxygen conditions. You also make two mutant constructs, with deletions in either the 5' UTR or the 3' UTR. The results are summarized below: Green Fluorescence: Hi O2 3'UTR Low Lo O2 High 5'UTR GFP 100 bps GFP Low High GFP 100 bps High High Diagram the position of a cis-acting site for the regulation of Oxy1 in response to oxygen. Does this site mediate the action of a POSITIVE or a NEGATIVE regulator? iii) Outline a molecular mechanism by which a protein binding to this region could influence gene expression in a manner that is consistent with all of the results shown in this problem.
