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.
Claims2
An in vitro method for identifying an agent that can alter the activity of the human CRF2α receptor promoter, the method comprising the steps of:
- (a) providing a host cell in vitro that comprises a vector comprising a polynucleotide and a heterologous reporter gene operably linked to the polynucleotide, the polynucleotide being selected from the group consisting of nucleotides 46 to 3943 of SEQ ID NO:2, nucleotides 539 to 3943 of SEQ ID NO:2, nucleotides 1061 to 3943 of SEQ ID NO:2, nucleotides 1598 to 3943 of SEQ ID NO:2, nucleotides 2038 to 3943 of SEQ ID NO:2, nucleotides 2569 to 3943 of SEQ ID NO:2, nucleotides 3104 to 3943 of SEQ ID NO:2, nucleotides 3598 to 3943 of SEQ ID NO:2, nucleotides 3649 to 3943 of SEQ ID NO:2, nucleotides 3739 to 3943 of SEQ ID NO:2, and nucleotides 3840 to 3943 of SEQ ID NO:2;
- (b) exposing the cell to a test agent;
- and
- (c) measuring and comparing the reporter gene expression level to that of a control cell that is not exposed to the test agent wherein a higher or lower expression level than that of the control cell indicates that the agent can alter the activity of the human CRF2α receptor promoter.
An in vitro method for identifying an agent that can alter the activity of the human CRF2α receptor promoter, the method comprising the steps of:
- (a) providing a host cell in vitro that comprise a vector comprising a functional fragment of the human CRF2α receptor promoter comprising SEQ ID NO:2 and a heterologous reporter gene operably linked to the functional fragment;
- (b) exposing the cell to a test agent;
- and
- (c) measuring and comparing the reporter gene expression level to that of a control cell that is not exposed to the test agent wherein a higher or lower expression level than that of the control cell indicates that the agent can alter the activity of the human CRF2α receptor promoter.
