Construct: Amino acid replacement: V349C. This amino acid change is to the one found in the equivalent residue in βTub85D.
βTub56D::βTub85Dβ1-β2.iv, βTub85Dn has spermatid axoneme phenotype
The addition of βTub56D::βTub85Dβ1-β2.iv to βTub85Dn homozygotes leads to almost wild-type axoneme morphology in the testis - in distal sections however many axonemes lose any discernable organisation.
