G protein-coupled receptor 3 (Gpr3) is a member of G protein-coupled receptor rhodopsin family, which is present throughout the follicle within the ovary and functions as a critical factor for the maintenance of meiotic prophase arrest in oocytes by a Gs protein-mediated pathway. In the current paper, attempts were made to clone and characterize a gene encoding Gpr3 from pigs and investigate its expression pattern in tissues and the whole cumulus–oocyte complexes (COCs) in vitro maturation (IVM… 
Sphingosine 1-phosphate acts as an activator for the porcine Gpr3 of constitutively active G protein-coupled receptors
Findings suggest the porcine Gpr3, Gpr6, and Gpr12 genes are identified as a subfamily of G protein-coupled receptors, and porcines GPR3 was a constitutively active Gprotein-Coupled receptor.
Immunolocalization and expression pattern of Gpr3 in the ovary and its effect on proliferation of ovarian granulosa cells in pigs.
The stage- and cell-specific expression pattern of Gpr3 in the porcine ovary suggested that GPR3 might play an important role during the entire process of follicular development and luteinization.
Characterization of Four Orphan Receptors (GPR3, GPR6, GPR12 and GPR12L) in Chickens and Ducks and Regulation of GPR12 Expression in Ovarian Granulosa Cells by Progesterone
The data reveal the structure, function, and expression of GPR3, GPR6, G PR12, and GPR12L in birds, thus providing the first piece of evidence that GPR 12 expression is upregulated by gonadal steroid (i.e., progesterone) in vertebrates.
FSH Modulates PKAI and GPR3 Activities in Mouse Oocyte of COC in a Gap Junctional Communication (GJC)-Dependent Manner to Initiate Meiotic Resumption
It is shown that FSH induces a transient increase in cAMP levels and regulates GJC to control PKAI and GPR3 activities, thereby creating an inhibitory phase after PDE3A and MAPK activities increase, meiosis resumes.
GPR3, GPR6, and GPR12 as novel molecular targets: their biological functions and interaction with cannabidiol
Identification of CBD as a new inverse agonist for GPR3, GPR6, and GPR12 provides the initial chemical scaffolds upon which potent and efficacious agents acting on these receptors can be developed, with the goal of developing chemical tools for studying these orphan receptors and ultimately new therapeutic agents.
Structural basis for the binding of a selective inverse agonist AF64394 with the human G-protein coupled receptor 3 (GPR3).
The three-dimensional structure and conformational dynamics of GPR3 complexed with the inverse agonist AF64394 are described, finding the Pose 1 as a very stable pose with the least fluctuation during the MD simulation while the Pose 2 underwent a significant fluctuation.
Identification of genes involved in breast cancer and breast cancer stem cells
It seems that several genes that are not directly related with hormone metabolism and basic signal transduction pathways might have an important role in relapse and disease progression and, thus, can be targeted for new treatment approaches for breast cancer.


Isolation and chromosomal localization of a novel human G-protein-coupled receptor (GPR3) expressed predominantly in the central nervous system.
Degenerate oligonucleotide primers designed against known G-protein-coupled receptors were used in polymerase chain reaction amplification to isolate a novel receptor sequence (R4) from a rat
Neural Expression of G Protein-coupled Receptors GPR3, GPR6, and GPR12 Up-regulates Cyclic AMP Levels and Promotes Neurite Outgrowth*
Results indicate that expression of the constitutively active GPCRs up-regulates cAMP production in neurons, stimulates neurite outgrowth, and counteracts myelin inhibition.
Expression of Growth Differentiation Factor 9 Messenger RNA in Porcine Growing and Preovulatory Ovarian Follicles1
It is concluded that GDF 9 mRNA can be produced by somatic follicular cells in the pig and that cumulus expansion is not preceded or accompanied by an increase in the RA of GDF9 mRNA in any of the tested cell types.
Oocyte-specific expression of Gpr3 is required for the maintenance of meiotic arrest in mouse oocytes.
Molecular cloning of an orphan G-protein-coupled receptor that constitutively activates adenylate cyclase.
The mouse ACCA (mACCA) was therefore recloned by PCR, and expression of mACCA in Cos-7 cells demonstrated that the mouse receptor behaved similarly as a constitutive activator of adenylate cyclase.
GPR3 may not be a potential candidate gene for premature ovarian failure.
Meiotic Arrest in Human Oocytes Is Maintained by a Gs Signaling Pathway1
It is demonstrated that human oocytes maintain meiotic arrest prior to the LH surge using a signaling pathway similar to that of rodent oocytes.
