Plays a role in the quality control of integral membrane proteins. Degrades membrane proteins in a processive manner starting at either the N- or C-terminus; recognition requires a cytoplasmic tail of about 20 residues with no apparent sequence requirements.

It degrades ceratin membrane proteins that have not been assembled into complexes such as SecY, F0 ATPase subunit a and YccA, as well as cytoplasmic proteins sigma-32, LpxC, KdtA and phage lambda cII protein. Degrades C-terminal-tagged cytoplasmic proteins which are tagged with an 11-amino-acid nonpolar destabilizing tail via a mechanism involving the 10SA (SsrA) stable RNA.
