DESCRIPTION

Also known as AGRG1_MOUSE, Adgrg1, Cyt28, Gpr56. Receptor involved in cell adhesion and probably in cell-cell interactions. Mediates cell matrix adhesion in developing neurons and hematopoietic stem cells. Receptor for collagen III/COL3A1 in the developing brain and involved in regulation of cortical development, specifically in maintenance of the pial basement membrane integrity and in cortical lamination (PubMed:21768377). Binding to the COL3A1 ligand inhibits neuronal migration and activates the RhoA pathway by coupling to GNA13 and possibly GNA12 (By similarity). Plays a role in the maintenance of hematopoietic stem cells and/or leukemia stem cells in bone marrow niche (PubMed:23478665). Plays a critical role in tumourigenesis (By similarity). Plays essential role in testis development (PubMed:20981830). Predominantly non-covalently linked heterodimer of the N-terminal and the C-terminal fragment. ADGRG1 NT self-associates in a trans-trans manner; the homophilic interaction enhances receptor signaling. ADGRG1 CT interacts with ARRB2; the interaction is impaired by ADGRG1 NT. Part of a GPCR-tetraspanin complex at least consisting of ADGRG1, CD81, eventually CD9, and GNA11 in which CD81 is enhancing the association of ADGRG1 with GNA11 (By similarity). Interacts with heparin; leading to the reduction of ADGRG1 shedding (PubMed:27068534). Interacts with COL3A1 (By similarity).
