General annotation (Comments)
| Function | Calcium-independent receptor of high affinity for alpha-latrotoxin, an excitatory neurotoxin present in black widow spider venom which triggers massive exocytosis from neurons and neuroendocrine cells. Receptor for TENM2 that mediates heterophilic synaptic cell-cell contact and postsynaptic specialization. Receptor propably implicated in the regulation of exocytosis By similarity. |
| Subunit structure | Forms a heterodimer, consisting of a large extracellular region (p120) non-covalently linked to a seven-transmembrane moiety (p85). Interacts with syntaxin and with proteins of the SHANK family via the PDZ domain By similarity. |
| Subcellular location | Cell membrane; Multi-pass membrane protein. Cell projection › axon By similarity. Cell projection › growth cone By similarity. Cell junction › synapse By similarity. Cell junction › synapse › presynaptic cell membrane By similarity. Cell junction › synapse › synaptosome By similarity. Note: Colocalizes with TENM2 on the cell surface, across intercellular junctions and on nerve terminals near synaptic clefts By similarity. |
| Domain | The extracellular domain coupled to the a single transmembrane region are sufficient for full responsiveness to alpha-latrotoxin By similarity. |
| Post-translational modification | Autoproteolytically cleaved into 2 subunits, an extracellular subunit and a seven-transmembrane subunit. This proteolytic processing takes place early in the biosynthetic pathway, either in the endoplasmic reticulum or in the early compartment of the Golgi apparatus By similarity. |
| Sequence similarities | Belongs to the G-protein coupled receptor 2 family. LN-TM7 subfamily. Contains 1 GPS domain. Contains 1 olfactomedin-like domain. Contains 1 SUEL-type lectin domain. |
