There are also many other differences in the number or coding sequences of ankyrin repeat genes between wMel strain genomes and wAu [21], [49](see also [15] and [48] for sequence of wMelCS). (journals.plos.org)
This early work was followed by postdoctoral studies at Duke University, where he identified a novel and conserved role for the membrane skeletal protein ankyrin in post-Golgi delivery of membrane proteins to the plasma membrane in epithelial cells and photoreceptors. (brightfocus.org)
The active ingredient comprises several DARPins (designed ankyrin repeat proteins). (sciencedaily.com)
