ATP-dependent Clp protease proteolytic subunit, mitochondrial (CLPP)

Protease part of the Clp complex that cleaves peptides and various proteins within an ATP-dependent process. Has low peptidase activity in the absence of CLPX.

The Clp complex can degrade CSN1S1, CSN2 and CSN3, as well as synthetic peptides (in vitro) and could be responsible for a fairly general and central housekeeping function rather than for the degradation of specific substrates. .
