Amino acid change:

W324term | Lis-1-PA; W324term | Lis-1-PB; W324term | Lis-1-PF; W324term | Lis-1-PG

Reported amino acid change:

W324term

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

Only 2% of Ecol\lacZarm.PV-negative germline stem cells remain three weeks after Lis-1D clone induction, compared to 75-80% in wild-type clones. Apoptotic Lis-1D mutant germline stem cells are not found, indicating that Lis-1 is required for controlling germline stem cell self-renewal but not survival in the ovary.

Lis-1D mutant germline stem cells produce fewer germline cysts than control germline stem cells. The percentage of BrdU-positive Lis-1D mutant germline stem cells is similar or even higher than that of control germline stem cells. Lis-1D mutant germline stem cells exhibit a misoriented spindle more frequently than control germline stem cells.

Lis-1D heterozygous germaria have about one cystoblast, as in wild-type germaria.

Females containing homozygous germ line clones fail to produce any eggs. No vitellogenic oocytes are seen in the ovaries.

Lis-1D heterozygous germaria overexpressing tkvca.Scer\UAS.P\T under the control of Scer\GAL4nos.UTR.T:Hsim\VP16 exhibit significantly fewer cystoblasts than wild-type germaria overexpressing tkvca.Scer\UAS.P\T.

Expression of constitutively active tkvQ199D.Scer\UAS.P\T in Lis-1D heterozygous germaria under the control of Scer\GAL4nos.UTR.T:Hsim\VP16 slows the loss of two week old Lis-1D mutant germline stem cells dramatically. This rescue effect becomes less dramatic for 3 week old mutant germline stem cells.

Germline specific expression of shgScer\UAS.P\T.cCa under the control of Scer\GAL4nos.UTR.T:Hsim\VP16 slows the loss of 2 week old Lis-1D mutant germline stem cells dramatically and the rescue effect is also decreased for the 3 week old mutant germline stem cells.
