domain:The extracellular domain coupled to the a single transmembrane region are sufficient for full responsiveness to alpha-latrotoxin.,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 propably implicated in the regulation of exocytosis.,PTM:Proteolytically 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.,similarity:Belongs to the G-protein coupled receptor 2 family. LN-TM7 subfamily.,similarity:Contains 1 GPS domain.,similarity:Contains 1 olfactomedin-like domain.,similarity:Contains 1 SUEL-type lectin domain.,subunit: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.,
