title: Functional properties of the epithelial Ca2+ channel, ECaC.
abstract: ECaC is the first member of a new subfamily of Ca2+ channels embedded in the large TRPC family that includes numerous channel proteins. The channel has been proposed as the main gatekeeper of transcellular Ca2+ transport in kidney and intestine. The functional characterization of this channel is evolving rapidly and may have far reaching consequences for other channels of the TRPC family. The goal of this mini-review is to summarize the major functional and structural characteristics of ECaC, including (i) its proposed functional role, (ii) its channel structure and expression pattern, (iii) its main electrophysiological characteristics and (iv) its regulation.
