Functional interaction between InsP3 receptors and store-operated Htrp3 channels
It is shown that Htrp3 channels stably expressed in HEK293 cells are in a tight functional interaction with the InsP3 receptors, providing evidence for the coupling hypothesis, in which InsP 3 receptors activated by InsP2 interact with SOC and regulate Icrac.

It is implied that constitutively active TRPC3-type channels, which are up-regulated in TRPC6-deficient smooth muscle cells, are not able to functionally replace TRPC 6, which has distinct nonredundant roles in the control of vascular smooth muscle tone.

It is concluded that insP3Rs mediate both SOC and TRP channel opening and that the InsP3R is essential for maintaining coupling between store emptying and physiological activation of SOCs.

It is proposed that Orai proteins by interacting with TRPCs act as regulatory subunits that confer STIM1-mediated store depletion sensitivity to these channels.

The data support the view that both CaM and IP3Rs play important roles in controlling the gating of Trp-based channels, however, the sensitivity and responses toCaM andIP3Rs differ for each Trp.
