To investigate the relationship between SNC19 protein and cancer metastasis.Expression of SNC19 protein in cancer cell lines and tissues was examined by Western blot analysis using anti-SNC19 monoclonal antibody. In addition, Psectag2A-SNC19(ORF) eukaryotic expression vector was constructed and transfected into BCAP37 cells. After the target protein was expressed and purified, processing forms of SNC19 protein were further identified using anti-His mAb and each form was assayed for its gelatinase activity.Different expression and post-translational processing of the SNC19 proteins in the cancer cell lines and intestinal tissues were detected.BCAP37 cells transfected full-length SNC19 (ORF) generated two different sized proteins in cell lysates, 120 and 75 kD; 75 kD was detected to have proteolytic activity by gelatin zymography.SNC19 protein presents different expression and post-translational processing in the cancer cells and tissues, of which 75 kD was identified to have gelatinase activity.
