CHRM3 and malignant colon neoplasm: Rosemond et al. [34] reported that TMEM147 is a binding protein of M3R M3 muscarinic acetylcholine receptor and might act as a potent negative regulator of M3R function by changing the stimulatory effects of carbachol on H508 human colon cancer cell proliferation and p90 ribosomal S Kinase (p90RSK) activation.
