TRP Ion Channels--Two Proteins in One

Abstract
It is well established that some proteins carry out more than one job in the cell, but so far, ion channels do not appear to exhibit this versatility. In their Perspective, Levitan and Cibulsky discuss a cluster of new findings showing that two members of the long TRP ion channel family, LTRPC7 and LTRPC2, are both ion channels and enzymes.
