Abstract
A new secreted yeast glycoprotein with an Mr of about 400 kDa (gp400) has been found. The glycoprotein is an O-mannosylated oligomer, whose synthesis and export into culture medium are stimulated by heat shock. Intracellular transport of gp400 is carried out by membrane vesicles distinct from the known constitutive secretory vesicles. Immunological analysis revealed gp400 only in Saccharomyces species.
摘要
已发现一种新的分泌型酵母糖蛋白，其分子量约为400 kDa（gp400）。该糖蛋白是一种O-甘露糖基化寡聚物，其合成及向培养基中的分泌受热休克刺激。gp400的细胞内运输由不同于已知组成型分泌囊泡的膜囊泡进行。免疫分析表明gp400仅存在于酿酒酵母属物种中。
