Contains ncd sequences (expressed under the control of the ncd promoter) encoding a protein lacking amino acids 183 to 247 (approximately one-third of the predicted α-helical coiled-coil stalk region).
Embryos derived from ncd1/ncd1 ncdMC2/ncdMC2 females have curved or bent spindles and split centrosomes at one or both spindle poles.
ncdMC2 partially rescues ncd1
