SEC12

SED2, Sar family guanine nucleotide exchange factor SEC12, L000001837, YNR026C
Guanine nucleotide exchange factor (GEF); activates Sar1p by catalyzing the exchange of GDP for GTP; required for the initiation of COPII vesicle formation in ER to Golgi transport; glycosylated integral membrane protein of the ER; SEC12 has a paralog, SED4, that arose from the whole genome duplication

ERN1, bifunctional endoribonuclease/protein kinase IRE1, L000000875, YHR079C
Serine-threonine kinase and endoribonuclease; transmembrane protein that mediates the unfolded protein response (UPR) by regulating Hac1p synthesis through HAC1 mRNA splicing; role in homeostatic adaptation to ER stress; Kar2p binds inactive Ire1p and releases from it upon ER stress

Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Evidence for the intimate relationship between vesicle budding from the ER and the unfolded protein response.

Sato M, Sato K, Nakano A

Yeast Saccharomyces cerevisiae Sec12p, an ER membrane protein, carries out an essential function as the guanine nucleotide exchange factor of the small GTPase Sar1p. Sar1p-GTP is pivotal for the assembly of a coat protein complex, COPII, on the ER membrane, and thus Sec12p can be regarded as the initiator of vesicle budding from the ER. In an effort to identify ... [more]
