Amino acid replacement: V531D.
A single amino change in the DH domain of pblΔN-term.UAS.Tag:HA compromises its catalytic activity.
Scer\GAL4e22c-mediated expression of pblDH-PH-V531D.Scer\UAS.T:Ivir\HA1 results in 1.4% embryonic lethality with 0% of embryos showing some loss of naked cuticle on the ventral side.
Expression of pblDH-PH-V531D.Scer\UAS.T:Ivir\HA1 in the mesoderm of stage 8 embryos under the control of the Scer\GAL4twi.2PE and Scer\GAL4Mef2.PR drivers does not produce any mesodermal migration or invagination defects.
Expression of pblDH-PH-V531D.Scer\UAS.T:Ivir\HA1 in the eye under the control of the Scer\GAL4GMR.PU driver does not produce any obvious eye defects.
Scer\GAL4arm.PS/pblDH-PH-V531D.UAS.Tag:HA is a non-suppressor of embryonic/larval cuticle | ventral phenotype of Scer\GAL4arm.PS, armS10.UAS.Tag:MYC
Scer\GAL4arm.PS/pblDH-PH-V531D.UAS.Tag:HA is a non-suppressor of abdominal ventral denticle belt phenotype of Scer\GAL4arm.PS, armS10.UAS.Tag:MYC
Co-expression of pblDH-PH-V531D.Scer\UAS.T:Ivir\HA1 does not suppress the excess naked cuticle phenotype seen in Scer\GAL4arm.PS armS10.Scer\UAS.T:Hsap\MYC embryos.
Scer\GAL4twi.2PE/pblDH-PH-V531D.UAS.Tag:HA fails to rescue pbl3
Expression of pblDH-PH-V531D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4twi.2PE fails to rescue the mesodermal migration defects seen in pbl3 homozygous mutants.
