FZO1

mitofusin, L000004083, YBR179C
Mitofusin; integral membrane protein involved in mitochondrial outer membrane tethering and fusion; role in mitochondrial genome maintenance; efficient tethering and degradation of Fzo1p requires an intact N-terminal GTPase domain; targeted for destruction by the ubiquitin ligase SCF-Mdm30p and the cytosolic ubiquitin-proteasome system

NUM1

PAC12, L000001287, YDR150W
Protein required for nuclear migration; component of the mitochondria-ER-cortex-ancor (MECA); required for the association of mitochondria with the cell cortex and for accurate distribution of mitochondrial network; interacts with Mdm36p to link the ER and motochondria at the cortex; localizes to the mother cell cortex and the bud tip; may mediate interactions of dynein and cytoplasmic microtubules with the cell cortex

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.

Endoplasmic reticulum-associated mitochondria-cortex tether functions in the distribution and inheritance of mitochondria.

Lackner LL, Ping H, Graef M, Murley A, Nunnari J

To elucidate the functional roles of mitochondrial dynamics in vivo, we identified genes that become essential in cells lacking the dynamin-related proteins Fzo1 and Dnm1, which are required for mitochondrial fusion and division, respectively. The screen identified Num1, a cortical protein implicated in mitochondrial division and distribution that also functions in nuclear migration. Our data indicate that Num1, together with ... [more]

Phenotypic Enhancement
Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.
