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.
3D structures of SRPR
Updated on 13-August-2013
1nrj – ySRPR α+β subunits + GTP – yeast
2fh5 - hSRPR α+β subunits + GTP – human
2ged - ySRPR β subunit (mutant)
2go5 - hSRPR α subunit + mSRPR β subunit + ribosomal proteins L23, L31, L35 + dSRP19 + dSRP54 + RNA - EM
