摘要：

Luminal endoplasmic reticulum (ER) proteins carry a sorting signal that allows them to be retrieved from the Golgi apparatus by a specific receptor. In yeast, this receptor is encoded by the ERD2 gene. Although retrieval of ER proteins does not appear to be an essential process, cells lacking ERD2 do not grow. Several multicopy suppressors of this growth defect have been isolated. The sequence of one of these, SED6, is presented here. Its product contains motifs characteristic of methyltransferases, and it is identical to ERG6, the presumed structural gene for S-adenosylmethionine:Delta(24)-sterol-C-methyltransferase. The gene is located adjacent to PDR4, near the centromere of chromosome XIII.
