Description

20bp deletion in the coding sequence, together with an insertion of 14bp of novel sequence that generates a truncated protein predicted to lack the entire C-terminal region as well as a portion of the acetyltransferase domain.

Detailed Description

Reference

vnc14/vncBDk females produce fewer eggs than wild type, the majority of which are shortened along the anterior/posterior axis and collapsed. Eggs laid by 28.2% of the mutant females have defects in the shape or position of the dorsal appendages, such as appendages that are closely apposed or fused. 38.5% of egg chambers that appear to be at stage 11 or older based on follicle cell morphology contain unusually small oocytes and persistent nurse cells, phenotypes typically resulting from a failure of nurse cells to dump their contents into the oocyte. 13.3% of vnc14/vncBDk egg chambers contain abnormal numbers of germline cells showing both defects in cystocyte division and in cyst encapsulation. Fusome defects are seen in 28.3% of vnc14/vncBDk germaria. Chromatin reorganisation in the nurse cell nuclei is disrupted in mutant egg chambers, with many of the nurse cells beyond stage 5 retaining the condensed "five-blob" configuration of chromatin (70.3%) in contrast to wild-type nurse cells at this stage (3.2%).

Homozygous female germline clones have not been recovered. Homozygous clones induced late in the wing disc are significantly smaller than their wild-type twin spots. Early induction of clones results in large wild-type twin spots in the wing disc without any accompanying mutant clone.
