Data class Domain
Predictors PROSITE; PS51876; PV_NPRO
Names Pestivirus N-terminal protease (Npro) domain; Peptidase C53 domain
Function The pestivirus N-terminal protease Npro is a cysteine autoprotease that cleaves between its own C-terminus and the N-terminus of the core protein. Following the first cleavage reaction, Npro does not possess any proteolytic trans-activity but acts as a viral immediate effector to modulate the host cell's antiviral defenses.
