FFAR2 and FFAR3 interact to form a heteromer in primary monocytes and macrophages via proximity ligation assay, and during heterologous expression in HEK293 cells via bimolecular fluorescence complementation and fluorescence resonance energy transfer. FFAR2 and FFAR3 may interact to form a receptor heteromer with signaling that is distinct from the parent homomers.

Data suggest that cytokines TNFalpha and interleukin-1b markedly reduce GPR120/FFAR4 expression in adipocytes; in contrast, these cytokines induce expression of GPR84 and GPR41/FFAR3 in adipocytes. These studies were conducted in adipocytes cultured from subcutaneous adipose tissue. (GPR = G-protein coupled receptor; FFAR = free fatty acid receptor)

Title: Human GPR42 is a transcribed multisite variant that exhibits copy number polymorphism and is functional when heterologously expressed.

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.
