Differential processing and turnover of the oncogenically activated neu/erb B2 gene product and its normal cellular counterpart.

Abstract excerpt

In nontransformed DHFR/G-8 cells (NIH 3T3 cells transfected with normal rat neu gene), the normal neu gene product was initially synthesized as a 170-kDa protein bearing endoglycosidase H-sensitive oligosaccharide chains and was then processed to a 175-kDa mature form with endoglycosidase H-resistant, endoglycosidase F-sensitive oligosaccharide chains. Most of this 175-kDa mature form appeared on the cell surface...
