Gene duplication and functional divergence of the zebrafish insulin‐like growth factor 1 receptors
16 May 2006
Abstract excerpt
Insulin-like growth factor (IGF) 1 receptor (IGF1R)-mediated signaling plays key roles in growth, development, and physiology. Recent studies have shown that there are two distinct ig f1r genes in zebrafish, termed ig f1ra and ig f1rb. In this study, we tested the hypothesis that zebrafish ig f1ra and ig f1rb resulted from a gene duplication event at the ig f1r locus and that this has led to their functional...
