Abstract
The rat asialoglycoprotein receptor (ASGP-R) has been expressed in cultured rat hepatoma cells (HTC cells) after transfection with cloned cDNAs. Fluorescence-activated cell sorting of transfected cells was used to identify the functional cDNA clones and to isolate cells expressing the ASGP-R. Simultaneous or sequential transfections with two cloned cDNAs that encode related but distinctive polypeptide chains were needed to obtain ASGP-R activity; transfection with either cDNA alone failed to produce detectable ASGP-R. The affinity of transduced ASGP-R for asialo orosomucoid is less than that of the native rat ASGP-R, and the number of surface receptors in clones expressing ASGP-R is about one-fifth that found on rat hepatocytes.Entities:
