title: [Proteins of the nuclear matrix and their phosphorylation in normal and tumor cells].
abstract: The protein composition of the nuclear matrix of normal and tumor cells is discussed. A characteristic feature of the latter is the predominance of high molecular weight polypeptides containing mainly glyco- and phosphoproteins. Only few of them are identified. Nuclear matrix preparations from tumors differ by the presence of fibronectin and phosphotyrosine-containing proteins with a molecular mass of nearly 180 and 170 kDa as well as of high turnover of high molecular weight protein group and inhibition of their biosynthesis by chloramphenicol.
