    • 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.
    • 公众人类基因组数据库的搜索确定了人类EST,GenBank登录号AW293249,其与已知的河豚urocortin序列具有高同源性。 从人类基因组DNA扩增全长序列并进行测序。 新序列与人尿皮质素I和尿皮质素II的序列同源性比较显示,该序列编码了一种新的人类urocortin,其命名为urocortin III(UcnIII)。 虽然urocortin III对CRF-R1或CRF-R2没有高亲和力,但CRF-R2的亲和力大于对CRF-R1的亲和力。 Urocortin III能够刺激表达CRF-R2α或bgr的细胞中的环AMP产生。 因此,亲和力足够高,使得尿皮质素III可以作为CRF-R2的天然激动剂。 然而,urocortin III也可能是未被鉴定的受体的更强的激动剂。
