Adaptive changes in the transcription factor HoxA-11 are essential for the evolution of pregnancy in mammals
22 Sept 2008
Abstract excerpt
Evolutionary change in gene regulation can result from changes in cis-regulatory elements, leading to differences in the temporal and spatial expression of genes or in the coding region of transcription factors leading to novel functions or both. Although there is a growing body of evidence supporting the importance of cis-regulatory evolution, examples of protein-mediated evolution of novel developmental...
