Putative G-protein coupled receptor 42 (previously termed FFAR1L, FFAR3L, GPR41L, and GPR42P) is a protein that in humans is encoded by the GPR42gene.[5][6] The human GPR gene is located at the same site as the human FFAR1, FFAR, and FFAR3 genes, i.e., on the long (i.e., "q") arm of chromosome 19 at position 23.33 (notated as 19q23.33). This gene appears to be a segmental duplication of the FFAR3 gene. The human GPR42 gene codes for several proteins with a FFAR3-like structure but their expression in various cell types and tissues as well as their activities and functions have not yet been clearly defined in any scientific publication followed by PubMed as of 2023.[7][8][9][10]
