Most vib1105 homozygous somatic clones in the larval brain show variable numbers of type I and type II neuroblasts (absent or ectopic), as compared to control clones.
vib1105/vibj5A6 transheterozygous larval brain neuroblasts frequently display defective asymmetric cell divisions, as compared to controls: aPKC, Par6, and Gαi, but not Baz, Insc, Pins and Cdc42, fail to localize to a strong apical cortex crescent during metaphase; Mira, Pros, Brat, Numb and Pon fail to localize to a strong basal cortex crescent during metaphase; and the mitotic spindle axis is misoriented with respect to the neuroblast polarity.
vib1105 is partially rescued by vibUAS.Venus/Scer\GAL4elav.PLu
