Latrofilin-2 je protein koji je kod ljudi kodrian LPHN2 genom.^[1]^[2]

Ovaj protein je član latrofilinske familije G protein spregnutih receptora (GPCR). Latrofilini mogu da učestvuju u ćelijskoj adheziji i u prenosu signala. Endogeno proteolitičko razlaganje unutar cisteinom bogatog GPS (GPCR proteolizno mesto) domena proizvodi dve podjedinice (veliku ekstracelularnu N-terminalnu adhezionu jedinicu i podjedinicu koja je u znatno meri slična sa sekretinskom/kalcitoninskom familijom). Ovi domeni su nekovalentno vezani na ćelijskoj membrani. Dok je nekoliko transkriptnih varijanti poznato, do sada je samo jedna biološki okarakterisana.^[2]
