Latrophilin 1/LPHN1 Proteins and Enzymes

Latrophilin-1 is a brain-specific Orphan-B Receptor that binds alpha-latrotoxin, a potent presynaptic neurotoxin present in the venom of the black widow spider, in a Ca2+-independent manner. As with the other two latrophilins, it shares homology with lectin, olfactomedin, and transmembrane domains, and possesses variable C-termini and various alternative-splicing sites. CIRL is endogenously cleaved into two pieces at the GPCR proteolytic site (GPS) located adjacent to the first transmembrane ...
