A premature stop codon has been introduced into the SuUR sequences (at codon 361), resulting in the expression of a truncated protein from the construct.
female fertile, with Scer\GAL4c323
polytene chromosome, with Scer\GAL4AB1
Expression of SuUR1-360.Scer\UAS under the control of Scer\GAL4AB1 results in the disappearance of weak points in the polytene chromosomes of salivary glands.
Expression of SuUR1-360.Scer\UAS under the control of Scer\GAL4Sgs3.PD does not result in any changes in polytene chromosome morphology in the salivary gland.
