The molecular basis of capacitative (or store-operated) Ca 2+ entry is still subject to debate. The transient receptor potential proteins have been hypothesized to be structural components of store-operated Ca 2+ channels and recent evidence suggests that Trp3 and its closely related homolog Trp6 ar...
