Biosynthesis of lysosomal cathepsins B and H in cultured rat hepatocytes.


The biosynthesis of lysosomal cysteine proteases, cathepsins B and H, was investigated by using pulse-chase experiments in vivo in primary cultures of rat hepatocytes. Cathepsins B and H were isolated from either total cell extracts or culture medium labeled with [35S]methionine by immunoprecipitation and analyzed for their molecular forms. Within 60 min of… (More)
