Amino acid replacement: S863L.
Astral microtubules are detectable at any stage of the cell cycle in taccS863L.Ubi-p63E.T:Avic\GFP embryos, including anaphase, although spindle microtubules appear to be relatively normal. The mean spindle length in taccS863L.Ubi-p63E.T:Avic\GFP embryos is 13.2 υm, approximately 10% shorter than the mean length in wild-type embryos.
taccS863L.Ubi-p63E.GFP is a suppressor of lethal | embryonic stage phenotype of mars1/marsEP2477
The lethality of embryos laid by mars1/marsEP2477 mothers is rescued by taccS863L.Ubi-p63E.T:Avic\GFP expression.
taccS863L.Ubi-p63E.GFP partially rescues taccstella592
Expression of taccS863L.Ubi-p63E.T:Avic\GFP in a taccstella592 mutant background results in approximately 30% viability, with those embryos that do develop exhibiting a high incidence of mitotic defects, suggesting only partial rescue.
