| HGNC Family | G protein-coupled receptors |
| Name | olfactory receptor, family 51, subfamily G, member 1 (gene/pseudogene) |
| Description | Olfactory receptors interact with odorant molecules in the nose, to initiate a neuronal response that triggers the perception of a smell. The olfactory receptor proteins are members of a large family of G-protein-coupled receptors (GPCR) arising from single coding-exon genes. Olfactory receptors share a 7-transmembrane domain structure with many neurotransmitter and hormone receptors and are responsible for the recognition and G protein-mediated transduction of odorant signals. The olfactory receptor gene family is the largest in the genome. This olfactory receptor gene is a segregating pseudogene, where some individuals have an allele that encodes a functional olfactory receptor, while other individuals have an allele encoding a protein that is predicted to be non-functional.

{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\nAlthough the provided abstracts do not mention OR51G1 per se, they consistently describe the critical hemostatic roles of the platelet‐specific collagen receptor glycoprotein VI (GPVI). GPVI is central for mediating platelet adhesion to exposed subendothelial collagen at sites of vascular injury, thereby triggering rapid platelet activation, aggregation, and subsequent thrombus formation. In various injury models (e.g., FeCl₃‐induced injury and flow‐based adhesion assays), GPVI engagement is shown to determine the initiation and stability of the thrombus, while its deficiency or blockade is associated with protection against arterial thrombosis, even without a marked prolongation of bleeding time. This body of work emphasizes that GPVI cooperates with other collagen receptors—such as integrin α2β1—in a concerted manner to secure effective hemostasis and to limit pathological thrombosis."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "1", "end_ref": "9"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nBeyond its primary function as a collagen receptor, GPVI exhibits unexpected versatility by directly binding additional ligands such as fibrin and laminin. These interactions not only amplify thrombin generation and platelet recruitment to growing clots but also contribute to additional biological roles. For instance, GPVI engagement with polymerized fibrin promotes platelet procoagulant activity and clot stabilization, while its binding to laminin is implicated in promoting platelet spreading. Moreover, emerging evidence connects GPVI to non‐hemostatic processes such as cancer metastasis (via interaction with tumor‐expressed galectin‑3), modulation of inflammatory responses, and maintenance of vascular integrity during inflammatory challenges. Such alternative ligand interactions broaden the scope of GPVI in regulating vascular and immune homeostasis."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "10", "end_ref": "18"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nAt the molecular level, GPVI initiates robust intracellular signaling cascades via its immunoreceptor tyrosine‑based activation motif (ITAM)–associated Fc receptor γ‐chain. Engagement of GPVI triggers the activation of a series of kinases (such as Src, Syk, and PI3‑kinase isoforms including PI3Kα and –β) as well as adaptor proteins (including LAT, SLP‑76, and Lyn) that coordinate downstream events like phospholipase Cγ2 activation, calcium mobilization, granule secretion, and ultimately integrin activation. These tightly regulated signaling events are modulated by both positive regulators (e.g. Cbl‑b and pro‑signaling complexes such as those involving TRAF4) and negative regulators (such as TULA‑2 and CEACAM2) to ensure that platelet activation is robust yet self‐limiting.
