DPR1, FUS8, SCG2, SGP2, STE16, protein farnesyltransferase, L000001579, YDL090C
Beta subunit of the CAAX farnesyltransferase (FTase); this complex prenylates the a-factor mating pheromone and Ras proteins; required for the membrane localization of Ras proteins and a-factor; homolog of the mammalian FTase beta subunit

CAL1, CSD2, DIT101, KTI2, chitin synthase CHS3, L000000331, YBR023C
Chitin synthase III; catalyzes the transfer of N-acetylglucosamine (GlcNAc) to chitin; required for synthesis of the majority of cell wall chitin, the chitin ring during bud emergence, and spore wall chitosan; contains overlapping di-leucine and di-acidic signals that mediate, respectively, intracellular trafficking by AP-1 and trafficking to plasma membrane by exomer complex; requires AP-3 complex for its intracellular retention

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.

Publication

Yeast CAL1 is a structural and functional homologue to the DPR1 (RAM) gene involved in ras processing.

A 2.3-kilobase pair DNA fragment of the yeast CAL1 gene was cloned by complementation of the cal1-1 mutation, which causes a defect in nuclear division and bud formation (Ohya, Y., Ohsumi, Y., and Anraku, Y. (1984) Mol. & Gen. Genet. 193, 389-394). Nucleotide sequencing of this fragment revealed a single open reading frame (ORF) encoding a polypeptide of 376 amino ... [more]
