His scientific focus by then had shifted to exploring lipid and protein function in the internal membranes of skeletal muscle fibers. (sciencemag.org)
Here we will use it to seek evidence for an increased dependence of protein function on gene dosage upon aging. (ellisonfoundation.org)
In nature, advantageous amino acid substitutions may be promoted by positive selection, but the general structural distributions of positively selected mutations and their effects on protein function remain poorly examined. (sciencedaily.com)
