UASp regulatory sequences drive expression of the coding sequence of a βTub97EF isoform that contains the 4B exon (derived from the LP10436 cDNA clone).
female sterile, with Scer\GAL4VP16.mat.αTub67C
egg chamber, with Scer\GAL4VP16.mat.αTub67C
nucleus | oogenesis, with Scer\GAL4VP16.mat.αTub67C
nurse cell, with Scer\GAL4VP16.mat.αTub67C
Expression of βTub97EFUASp.4B.ORF under the control of Scer\GAL4VP16.mat.αTub67C results in dumpless egg chambers, with abnormal nurse cell nuclei.
