GPR32
protein-coding gene in the species Homo sapiens
G protein-coupled receptor 32, also known as GPR32 or the RvD1 receptor, is a human receptor (biochemistry) belonging to the rhodopsin-like subfamily of G protein-coupled receptors.
Gene
The GPR32 was initially identified and defined by molecular cloning in 1998 as coding for an orphan receptor, i.e. a protein with an amino acid sequence similar to known receptors but having no known ligand(s) to which it responds and no known function. The projected amino acid sequence of GPR32, however, shared 35-39% amino acid identity with certain members of the chemotactic factor receptor family, i.e. 39% identity with Formyl peptide receptor 1, which is a receptor for N-Formylmethionine-leucyl-phenylalanine and related N-formyl peptide chemotactic factors, and 35% identity with Formyl peptide receptor 2, which likewise is also a receptor for N-formyl peptides but also a receptor for certain lipoxins which are arachidonic acid metabolites belonging to a set of specialized proresolving mediators that act to resolve or inhibit inflammatory reactions. GPR32 mapped to chromosomal 19, region q13.3. There are no mouse or other orthologs of GPR32.
Receptor
The GPR32 protein is a G protein coupled receptor although the specific G protein subtypes which it activates has not yet been reported. GPR32 is expressed in human blood neutrophils, certain types of blood lymphocytes (i.e. activated CD8+ cells, CD4+ T cells, and T helper 17 cells), tissue macrophages, small airway epithelial cells, and adipose tissue.
This brief starts where responsible research should: with the source description of “GPR32” as protein-coding gene in the species Homo sapiens. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as protein-coding gene in the species Homo sapiens. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Oct 11, 2025. The linked authority identifier is Q18026401. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1998.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
- Current terminology
- Classification context
- Finding cited technical literature
Primary datasets, specimen catalogues, standards bodies and the most recent peer-reviewed literature.
Three-step research path
- Establish the record: confirm the title “GPR32”, its source revision and the description used here.
- Expand the search: follow GPR32 primary sources, GPR32 archive and GPR32 research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
Questions for further research
