Interaction between BiP and Sec63p is required for the completion of protein translocation into the ER of Saccharomyces cerevisiae.

The Journal of cell biology - 1 Dec 1995

Lyman S K, Schekman R

Abstract excerpt

To clarify the roles of Kar2p (BiP) and Sec63p in translocation across the ER membrane in Saccharomyces cerevisiae, we have utilized mutant alleles of the essential genes that encode these proteins: kar2-203 and sec63-1. Sanders et al. (Sanders, S. L., K. M. Whitfield, J. P. Vogel, M. D. Rose, and R. W. Schekman. 1992. Cell. 69:353-365) showed that the translocation defect of the kar2-203 mutant lies in the...
