Mutants of the CMP-sialic acid transporter causing the Lec2 phenotype.


Chinese hamster ovary (CHO) mutants belonging to the Lec2 complementation group are unable to translocate CMP-sialic acid to the lumen of the Golgi apparatus. Complementation cloning in these cells has recently been used to isolate cDNAs encoding the CMP-sialic acid transporter from mouse and hamster. The present study was carried out to determine the… (More)
