ubiquitin-protease pathway

ubiquitin-protease pathway

pathway in which a small protein cofactor, ubiquitin, couples with protein substrate to catalyze proteolytic destruction by proteases; this pathway is highly selective and tightly regulated and is responsible for protein degradation seen in muscle-wasting diseases.
