== Publication Abstract from PubMed == | |||
Squamous cell carcinoma antigen 1 (SCCA1), which belongs to serine proteinase inhibitor (serpin) superfamily, inhibits papain-like cysteine proteinase. Recently, it has been reported that SCCA1 acts not only as a proteinase inhibitor but also as an inhibitor of UV-induced apoptosis via suppression of the activity of c-Jun NH(2)-terminal kinase (JNK1). The present study determined the crystal structure of SCCA1, suggesting that the reactive center loop (RCL) of SCCA1, a recognition site of proteinase, is very flexible and located away form the main-body of SCCA1. We show that the inhibitory effect of SCCA1 on the kinase activity of JNK1 is lost when the RCL was truncated. Furthermore, we found that a mutant protein created by replacing one amino acid in RCL maintain the suppressive activity to JNK1, whereas the inhibitory effect to proteinase is obviously decreased. | |||
