title: Biochemical analysis of a 130,000 molecular weight glycoprotein on human melanoma cells.
abstract: A monomeric sialoglycoprotein of 130,000 molecular weight (gp 130) is a membrane protein detected by mouse monoclonal antibodies on human melanoma cells and in lesser amounts on a wide range of normal and malignant cell types. Eight monoclonal antibodies reacting with gp 130 detect at least four spatially distinct epitopes on the exposed surface of the gp 130 molecule. Biosynthetic studies have shown that gp 130 is synthesized through two precursor forms: a 100 kD glycosylated species and an 80 kD unglycosylated species, presumably the primary translational product of the encoding mRNA.
