STIM1 (stromal interaction molecule 1) regulates store-operated channels in the plasma membrane, but the regulation of TRPC (transient receptor potential canonical) heteromultimerization and location by STIM1 is poorly understood. STIM1 is a single transmembrane protein that communicates the filling state of the endoplasmic reticulum to store-operated channels. STIM1 has been reported to regulate the activity of all of the TRPC family members, except TRPC7. TRPC6 has been predominantly associated to second messenger-activated Ca2+ entry pathways. In the present paper we report that STIM1 regulates the expression of TRPC6 in the plasma membrane and evokes translocation of this channel to the endoplasmic reticulum. Attenuation of TRPC6 expression in the plasma membrane resulted in a reduction in the association of this channel with TRPC1 and TRPC3. We have found that expression of TRPC6 in the endoplasmic reticulum results in an increase in the passive Ca2+ efflux and basal cytosolic Ca2+ concentration, but not in the ability of cells to accumulate Ca2+ into the endoplasmic reticulum. We propose a novel mechanism for the regulation of TRPC6 channel location and function by STIM1, probably as a mechanism to modulate second messenger-operated Ca2+ entry while potentiating store-operated Ca2+ influx.

Ranked by citation count — the same ordering the engine uses when summing log1p(Cq) over citers.
DataRank blends this paper's own citation count with the influence of the papers that cite it. Here, roughly 55% comes from its base citations and 45% from the citation network (10 citing papers contributed measurable signal).
Citers are pulled from OpenAlex sorted by cited_by_count:descand capped per paper, so when the cap binds we keep the highest-signal references and the score is reproducible across reruns.
