'''Signal recognition particle receptor''' (SRPR) is associated with the endoplasmic reticulum.  SRPR is a receptor for the [[Signal recognition particle protein|signal recognition particle (SRP)]].  SRPR is a heterodimer with α and β subunits which contain a GTP-binding domain.  SRPR α subunit binds to SRP54 subunit of SRP complex.  SRPR β subunit is a transmembrane GTPase.  The bacterial SRPR is called '''FtsY'''.
