چکیده انگلیسی
A sequential immunocytochemical analysis of the human colon cancer cell line, LSB, demonstrated different localization of two proteins. C1GalT was localized in Golgi apparatus, while Cosmc was localized in endoplasmic reticulum. In contrast, the LSC cells, which do not have core 1 synthase activity due to a missense mutation in the Cosmc gene, did not express the C1GalT protein. Although the treatment with a proteasome inhibitor, lactacystin, of LSC cells resulted in the increased expression of C1GalT protein, the distribution of C1GalT was not in Golgi apparatus as seen in LSB cells. On the contrary, overexpression of Cosmc but not C1GalT lead to precise localization of C1GalT protein, which distributed in Golgi apparatus and recovered the core 1 synthase activity in LSC cells. These results suggest that the intracellular dynamics of C1GalT is controlled by its specific molecular chaperon, Cosmc, in association with core 1 synthase activity.
