Abstract
The DNA sequences of human and rat CRF2α receptor promoters are disclosed. Certain functional fragments of the human CRF2α receptor promoter are also disclosed. Further disclosed are a method of identifying functional fragments of human and rat CRF2α receptor promoters and a method of identifying agents that can alter the activity of the human or rat CRF2α receptor promoter.
Claims17
An isolated nucleic acid consisting of a polynucleotide selected from the group consisting of nucleotides 46 to 3943 of SEQ ID NO:2 and a fragment of nucleotides 46 to 3943 of SEQ ID NO:2 that comprises nucleotides 3840 to 3943 of SEQ ID NO:2.
A vector comprising:
- a nucleic acid that comprises nucleotides 3840 to 3943 of SEQ ID NO:2;
- and
- a heterologous reporter gene operably linked to the nucleic acid.
An isolated nucleic acid consisting of a functional fragment of nucleotides 46–3943 of SEQ ID NO:2 identified by a method comprising the steps of:
- (a) providing a vector that comprises a fragment of nucleotides 46–3943 of SEQ ID NO:2 and a heterologous reporter gene wherein the reporter gene is operably linked to the fragment;
- (b) introducing the vector into a suitable host cell;
- (c) measuring the reporter gene expression level;
- (d) comparing the gene expression level to a suitable negative control;
- and
- (e) identifying the fragment as a functional fragment if the gene expression level is at least twice as that of the negative control.
