Properties of the deoxycholate-solubilized HeLa cell plasma membrane receptor for binding group B coxsackieviruses.

ABSTRACT

Physical and chemical properties of deoxycholate-solubilized HeLa cell plasma membrane receptors for binding group B coxsackieviruses were determined. Receptors eluted from Sepharose 4B with an apparent molecular weight of 275,000 and sedimented with an S value of between 14.7 and 4.9 and a buoyant density of 1.06 to 1.10 g/cm3. Virus-binding activity was destroyed after treatment with proteases, glycosidases, and periodate but was unaffected by lipases or reducing or alkylating agents. Additionally, lectins, including concanavalin A, adsorbed receptors and inhibited virus attachment. The composite data suggested that glycoprotein is an integral part of the receptors for binding virus.
