Population
Picornaviral proteinases (2Apro and 3Cpro) and their cleavage sites
I
Intervention
Neural network algorithms combined with a surface exposure prediction algorithm

Prediction of cleavage sites in cellular proteins
A neural network-based method successfully predicts cleavage sites by picornaviral proteinases, providing a tool for discovering cellular targets.
Limitations
- Whether these proteins are indeed cleaved awaits experimental verification.
Cite This Study
Blom et al. (1996) studied Picornaviral polyprotein cleavage. Neural network algorithm and surface exposure prediction was evaluated on Sequence specificity and cleavage site prediction. A neural network approach successfully distinguished known picornaviral cleavage sites from noncleavage sites and predicted novel mammalian cellular targets for viral proteinases.
