The T786A mutation has been introduced into the par-1 coding region in par-1N1S.UASp.mGFP6.
Embryos from mothers expressing par-1T786A.N1S.Scer\UAS.P\T.T:Avic\GFP-m6 under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 exhibit abnormal centrosome location in cells of the epithelium, and enhances centrosomal microtubule asters, but does not have an apparent effect on basolateral microtubule bundles.
Expression of par-1T786A.N1S.Scer\UAS.P\T.T:Avic\GFP-m6 under the control of Scer\GAL4unspecified during oogenesis disrupts oocyte polarity; the nucleus is never localised to the dorsal/anterior corner of the oocyte as in wild type, but is instead mislocalised to the centre of the cell. Prior to the repolarisation of the oocyte, there is no effect on the organisation of the microtubules. However, at stage 9, the microtubule organisation is completely disrupted in the mutant oocytes; all cortex-associated microtubules appear to be missing.
