2L:16,681,017..16,681,017 [+]
Nucleotide change:

G16681017A

Amino acid change:

W100term | squ-PA; W100term | squ-PB; W100term | squ-PC

Reported amino acid change:

W100term

Comment:

G to A nucleotide change at the second or third position of the wild type Trp codon leads to a nonsense mutation (exact site of mutation unspecified). The mutation was annotated at the second base of the codon.

      Detailed Description
      Statement
      Reference

      squHE47/squPP32 females lay eggs with a range of dorsoventral patterning defects; 55.4% have a single dorsal appendage or the appendages are fused at the base, 44.2% have no dorsal appendage or are collapsed and only 0.4% are similar to wild type.

      (Pane et al., 2007)

      Most extreme eggs are spindle shaped without dorsal appendages. Other eggs have fused dorsal appendages or of normal morphology but remain unfertilized.

      squ[+]/squHE47 is a non-enhancer of abdominal segment phenotype of nanos+1+3.Tag:MS2, nanosBN

      Statement
      Reference

      nosBN,nos+1+3.T:MS2\MCP.BS/nosBN embryos carrying a squHE47/+ mutation do not display a reduction in abdominal segmentation compared to nosBN,nos+1+3.T:MS2\MCP.BS/nosBN embryos.

      (Becalska et al., 2011)

      The dorsoventral patterning defects seen in eggs derived from squHE47/squPP32 females are nearly completely suppressed if the females are also homozygous for lokp6; 9.3% have a single dorsal appendage or the appendages are fused at the base and 90.6% of the eggs are similar to wild type.

      (Pane et al., 2007)

      Mutation does not suppress the bicaudal phenotype of oskbcd.3UTR.T:Zzzz\His6.
