GPR39 is coupled to TMEM16a in intestinal fibroblast-like cells

Zeng, Fanning, Wind, Nicholas, Mcclengahan, Conor, Verkuijl, Martin, Watson, Robert and Nash, Mark (2012) GPR39 is coupled to TMEM16a in intestinal fibroblast-like cells. PLoS ONE, 7 (10). e47686.


GPR39 is a GPCR implicated as a regulator of gastrointestinal motility, although the mechanism remains elusive. Here, we report that GPR39 is expressed by a specific cell population cultured from mouse small intestine muscle layers, which was subsequently identified as fibroblast-like cells (FLCs) that have recently been shown to modulate gut motility. Application of the GPR39 agonist, Zn2+, induced large currents and membrane depolarization in FLCs cultured from wild-type mice, but not Gpr39−/− mice. This Zn2+-induced current could be suppressed by application of a TMEM16A antagonist, CaCCinh-A01, or by silencing Tmem16a expression. These data suggest that GPR39 might modulate gut motility via regulating TMEM16A function in FLCs.
