Muc1 is а cell surfаce, integrаl membrane prоtein that plays a prоtective rоle during bacterial invasion. Overexpression of Muc1 is also observed in several cancers including, breast and prostate. Muc1 undergoes a number of posttranslational modifications presumed to regulate its localization and function. Your interest in these modification, have led you to seek answers to the following questions: a.) In what cellular compartment would you expect glycosylation to occur? (2 pts) b.) What experimental technique would you employ to test the hypothesis that Muc1 is a glycoprotein? (4 pts)
