A search of the public human genome database identified a human EST, GenBank accession number AW293249, which has high homology to known pufferfish urocortin sequences. The full length sequence was amplified from human genomic DNA and sequenced. Sequence homology comparisons of the novel sequence with human urocortin I and urocortin II revealed that the sequence encoded a novel human urocortin, which was designated urocortin III (UcnIII). While urocortin III does not have high affinity for either CRF-R1 or CRF-R2, the affinity for CRF-R2 is greater than the affinity for CRF-R1. Urocortin III is capable stimulating cyclic AMP production in cells expressing CRF-R2α or β. Thus, the affinity is high enough that urocortin III could act as a native agonist of CRF-R2. However, it is also likely that urocortin III is a stronger agonist of a yet to be identified receptor.
