Signal recognition particle receptor (SRPR) is associated with the endoplasmic reticulum. SRPR is a receptor for the 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.
