[HTML][HTML] Expression cloning of a novel suppressor of the Lec15 and Lec35 glycosylation mutations of Chinese hamster ovary cells

FE Ware, MA Lehrman - Journal of Biological Chemistry, 1996 - ASBMB
Lec15 and Lec35 are recessive Chinese hamster ovary (CHO) cell glycosylation mutations
characterized by inefficient synthesis and utilization, respectively, of mannose-P-dolichol
(MPD). Consequently, Lec15 and Lec35 cells accumulate Man 5 GlcNAc 2-PP-dolichol and
glucosaminyl-acylphosphatidylinositol. This report describes the cloning of a suppressor
(termed SL15) of the Lec15 and Lec35 mutations from a CHO cDNA library by functional
expression in Lec15 cells, employing phytohemagglutinin/swainsonine selection. The SL15 …
