CC -!- FUNCTION: Receptor involved in cell adhesion and probably in cell-cell
CC interactions. Mediates cell matrix adhesion in developing neurons and
CC hematopoietic stem cells. Receptor for collagen III/COL3A1 in the
CC developing brain and involved in regulation of cortical development,
CC specifically in maintenance of the pial basement membrane integrity and
CC in cortical lamination. Binding to the COL3A1 ligand inhibits neuronal
CC migration and activates the RhoA pathway by coupling to GNA13 and
CC possibly GNA12. Plays a role in the maintenance of hematopoietic stem
CC cells and/or leukemia stem cells in bone marrow niche (By
CC similarity).Plays an essential role in testis development. Plays a
CC critical role in tumourigenesis. {ECO:0000250|UniProtKB:Q8K209,
CC ECO:0000250|UniProtKB:Q9Y653}.
CC -!- ACTIVITY REGULATION: ADGRG1 NT is proposed to inhibit receptor
CC signaling; its interactions with extracellular ligands and /or
CC homophilic ADGRG1 NT interactions may relieve the inhibition. Following
CC ligand binding to the N-terminal fragment, the N-terminal fragment is
CC released from the seven-transmembrane C-terminal fragment to unveil a
CC new N-terminal stalk, which then stimulates G-protein-dependent
CC signaling activity. The N-terminal stalk has also been shown to be
CC dispensable for at least some G-protein-dependent signaling.
CC {ECO:0000250|UniProtKB:Q9Y653}.
CC -!- SUBUNIT: Heterodimer of 2 chains generated by proteolytic processing;
CC the large extracellular N-terminal fragment (ADGRG1 NT) and the
CC membrane-bound C-terminal fragment (ADGRG1 CT) predominantly remain
CC associated and non-covalently linked. ADGRG1 NT self-associates in a
CC trans-trans manner; the homophilic interaction enhances receptor
CC signaling. ADGRG1-CT interacts with ARRB2; the interaction is impaired
CC by ADGRG1 NT. Interacts with TGM2; TGM2 probably is not a ADGRG1 ligand
CC and the interaction is reported controversial. Part of a GPCR-
CC tetraspanin complex at least consisting of ADGRG1, CD81, eventually
CC CD9, and GNA11 in which CD81 is enhancing the association of ADGRG1
CC with GNA11. Interacts with heparin; leading to the reduction of ADGRG1
CC shedding. Interacts with COL3A1 (By similarity).
CC {ECO:0000250|UniProtKB:Q9Y653}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q9Y653};
CC Multi-pass membrane protein {ECO:0000255}.
CC -!- SUBCELLULAR LOCATION: [ADGRG1 N-terminal fragment]: Secreted
CC {ECO:0000250|UniProtKB:Q9Y653}.
CC -!- SUBCELLULAR LOCATION: [ADGRG1 C-terminal fragment]: Membrane raft
CC {ECO:0000250|UniProtKB:Q9Y653}. Note=Interaction with its ligand COL3A1
CC leads to the release of ADGRG1 NT from the membrane and triggers the
CC association of ADGRG1 CT with lipid rafts.
CC {ECO:0000250|UniProtKB:Q9Y653}.
CC -!- PTM: Autoproteolytically cleaved into 2 fragments; the large
CC extracellular N-terminal fragment and the membrane-bound C-terminal
CC fragment predominantly remain associated and non-covalently linked.
CC Shedding to yield the secreted ADGRG1 N-terminal fragment seems to
CC involve metalloprotease(s). {ECO:0000250|UniProtKB:Q9Y653}.
CC -!- PTM: N-glycosylated. Contains sialic acid residues.
CC {ECO:0000250|UniProtKB:Q9Y653}.
CC -!- PTM: Ubiquitinated. Undergoes polyubiquitination upon activation.
CC {ECO:0000250|UniProtKB:Q9Y653}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 2 family. LN-TM7
CC subfamily. {ECO:0000305}.
