E51Q
embryonic neuroblast & spindle
ganglion mother cell GMC4-2a & spindle
Homozygotes show late embryonic lethality and show various abnormalities (like those seen in insc and raps mutants) which can be explained by defects in asymmetric divisions. 14% of GMC4-2a cells fail to divide and differentiate into a "large" RP2 neuron. 33% of GMC4-2a cells divide symmetrically (unlike in wild type) and give rise to two RP2s with equal nuclear size. Misorientation of the mitotic spindle is seen in GMC4-2a and in neuroblasts. Duplication of muscle DA1 can be seen. Strong RP2 neuron phenotypes are only seen in cdc2E51Q/Df(2L)J3 embryos if the cdc2E51Q allele is inherited from the mother (and not if it is inherited from the father).
