On the irnmn 1 arrival into lax; we encountered wake turbulence; which caused the autopilot to revert to control wheel pitch. There was some difficulty getting the aircraft back into VNAV path. This distraction resulted in us being about 900 feet low on our crossing restriction at the juuse intersection. No traffic conflict occurred and ATC did not say anything regarding our altitude.
