MAD1

coiled-coil domain-containing protein MAD1, L000000974, YGL086W
Coiled-coil protein involved in spindle-assembly checkpoint; required for inhibition of karyopherin/importin Pse1p (aka Kap121p) upon spindle assembly checkpoint arrest; phosphorylated by Mps1p upon checkpoint activation which leads to inhibition of anaphase promoting complex activity; forms a complex with Mad2p; gene dosage imbalance between MAD1 and MAD2 leads to chromosome instability

MPS2

MMC1, L000004546, L000004250, YGL075C
Essential membrane protein localized at nuclear envelope and SPBs; required for insertion of the newly duplicated spindle pole body into the nuclear envelope; potentially phosphorylated by Cdc28p; MPS2 has a paralog, CSM4, that arose from the whole genome duplication

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Ribosome biogenesis factors bind a nuclear envelope SUN domain protein to cluster yeast telomeres.

Horigome C, Okada T, Shimazu K, Gasser SM, Mizuta K

Two interacting ribosome biogenesis factors, Ebp2 and Rrs1, associate with Mps3, an essential inner nuclear membrane protein. Both are found in foci along the nuclear periphery, like Mps3, as well as in the nucleolus. Temperature-sensitive ebp2 and rrs1 mutations that compromise ribosome biogenesis displace the mutant proteins from the nuclear rim and lead to a distorted nuclear shape. Mps3 is ... [more]
