PTRF triggers a cave in. Academic Article uri icon

abstract

  • Caveolae are small membrane invaginations important for cell signaling that are characterized by the presence of caveolin proteins. Hill et al. (2008) have now identified PTRF as a new constituent of the caveolar coat. In the absence of PTRF, caveolae flatten and caveolin-1 is released into the cell membrane, where it is rapidly internalized and degraded.
