CC -!- FUNCTION: G-protein-coupled receptor that senses changes in the
CC extracellular concentration of calcium ions and plays a key role in
CC maintaining calcium homeostasis (By similarity). Senses fluctuations in
CC the circulating calcium concentration and modulates the production of
CC parathyroid hormone (PTH) in parathyroid glands (PubMed:7493018). The
CC activity of this receptor is mediated by a G-protein that activates a
CC phosphatidylinositol-calcium second messenger system (By similarity).
CC The G-protein-coupled receptor activity is activated by a co-agonist
CC mechanism: aromatic amino acids, such as Trp or Phe, act concertedly
CC with divalent cations, such as calcium or magnesium, to achieve full
CC receptor activation (By similarity). {ECO:0000250|UniProtKB:P41180,
CC ECO:0000269|PubMed:7493018}.
CC -!- ACTIVITY REGULATION: In resting state, adopts an open conformation,
CC anion-binding promoting the inactive configuration. Upon aromatic amino
CC acid-binding, the groove in the extracellular venus flytrap module is
CC closed, thereby inducing the formation of a novel homodimer interface
CC between subunits. Calcium ions stabilize the active state by enhancing
CC homodimer interactions between membrane-proximal domains to fully
CC activate the receptor. {ECO:0000250|UniProtKB:P41180}.
CC -!- SUBUNIT: Homodimer; disulfide-linked. Interacts with VCP and RNF19A (By
CC similarity). Interacts with ARRB1 (By similarity).
CC {ECO:0000250|UniProtKB:P41180, ECO:0000250|UniProtKB:P48442}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P41180};
CC Multi-pass membrane protein {ECO:0000250|UniProtKB:P41180}.

CC Name=A;
CC IsoId=Q9QY96-1; Sequence=Displayed;
CC Name=B;
CC IsoId=Q9QY96-2; Sequence=VSP_002036;
CC -!- TISSUE SPECIFICITY: Epidermis, kidney and cartilage.
CC {ECO:0000269|PubMed:10579354, ECO:0000269|PubMed:10625662,
CC ECO:0000269|PubMed:10652312, ECO:0000269|PubMed:9076582}.
CC -!- DOMAIN: The extracellular regions of the homodimer interact in a side-
CC by-side fashion while facing opposite directions. Each extracellular
CC region consists of three domains, LB1 (ligand-binding 1), LB2 and CR
CC (cysteine-rich). The two lobe-shaped domains LB1 and LB2 form a venus
CC flytrap module. In the inactive configuration, the venus flytrap
CC modules of both protomers are in the open conformation associated with
CC the resting state (open-open) and the interdomain cleft is empty. In
CC addition, each protomer contains three anions, which reinforce the
CC inactive conformation, and one calcium ion. In the active
CC configuration, both protomers of extracellular regions have the closed
CC conformation associated with agonist-binding (closed-closed). The
CC ligand-binding cleft of each protomer is solely occupied by an aromatic
CC amino-acid. Calcium is bound at four novel sites, including one at the
CC homodimer interface. Agonist-binding induces large conformational
CC changes within the extracellular region homodimer: first, the venus
CC flytrap module of each protomer undergoes domain closure. Second, the
CC LB2 regions of the two protomers approach each other, resulting in an
CC expansion of the homodimer interactions involving LB2 domains. Third,
CC the CR regions of the two subunits interact to form a large homodimer
CC interface that is unique to the active state. The CR regions are
CC brought into close contact by the motion involving LB2 since the two
CC domains are rigidly associated within each subunit.
CC {ECO:0000250|UniProtKB:P41180}.
CC -!- PTM: N-glycosylated. {ECO:0000250|UniProtKB:P41180}.
CC -!- PTM: Ubiquitinated by RNF19A; which induces proteasomal degradation.
CC {ECO:0000250|UniProtKB:P41180}.
CC -!- DISRUPTION PHENOTYPE: Heterozygous mice show benign and modest
CC elevations of serum calcium, magnesium and parathyroid hormone levels
CC as well as hypocalciuria. Homozygous mice show neonatal severe
CC hyperparathyroidism, had markedly elevated serum calcium and
CC parathyroid hormone levels, parathyroid hyperplasia, bone
CC abnormalities, retarded growth and premature death.
CC {ECO:0000269|PubMed:7493018}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 3 family.
CC {ECO:0000305}.
