| - | '''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.
