p53, besides being a tumor suppressor protein, is a transcription factor with a powerful activation domain. Mutation(s) in this gene is a frequent event in human carcinogenesis. Several of these mutations lead to loss of its function as transcription factor. Proteases are thought to play an important role in tumor invasion and metastasis by degradation of extra cellular matrices and basement membranes. The function of protein-coding genes is carried out by the protein product, it is important to study p53-dependent expression at the protein level. There are many factors which regulate the expression of proteases in the cell, however here in this review we have focused on the p53 gene and its regulatory effect on the expression of proteases.
