NUM1/YDR150W Summary Help

Standard Name NUM1 1
Systematic Name YDR150W
Alias PAC12 2
Feature Type ORF, Verified
Description 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 (1, 3, 4, 5)
