      Cohen, Shenhav Orit; Zhai, Bo; Gygi, Steven P.; Goldberg, Alfred L. (The Rockefeller University Press, 2012)
      During muscle atrophy, myofibrillar proteins are degraded in an ordered process in which MuRF1 catalyzes ubiquitylation of thick filament components (Cohen et al. 2009. J. Cell Biol. http://dx.doi.org/10.1083/jcb.200901052). ...
