data support a model whereby both bile acids and bilirubin contribute to cholestatic itch via agonism at MRGPRX4
Title: MRGPRX4 is a G protein-coupled receptor activated by bile acids that may contribute to cholestatic pruritus.
Taken together, these data strongly suggest that MRGPRX4 is a novel bile acid receptor that likely underlies cholestatic itch in human, providing a promising new drug target for anti-itch therapies.
Title: MRGPRX4 is a bile acid receptor for human cholestatic itch.
data indicate that genetic variation in MRGPRX4 contributes to inter-individual and inter-ethnic differences in the preference for mentholated cigarettes.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
