Amino acid change:

W1134term | hop-PA

Reported amino acid change:

W1134term

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

hop32/hop25 mutant flies die more rapidly than do wild-type controls following Drosophila C virus (DCV) infection, and contain about 10-fold more virus.

Compared with wild-type, hop32/hop25 mutant flies show decreased survival and contain significantly more virus particles when injected with Cricket Paralysis Virus (CrPV).

hop32/hop25 flies infected with Drosophila C virus have increased levels of viral RNA and viral capsid proteins than infected wild-type flies. hop32/hop25 flies show reduced survival compared to wild-type flies when injected with a low dose (1 x 102 LD50) of Drosophila C virus.

hop25/hop32 animals have an ectopic vein near the posterior crossvein of the wing.

There is no nuclear translocation of Stat92E protein into the nuclei of cells in the fat body in response to challenge with bacteria in hop25/hop32 mutant adult flies.

hop25/hop32 females show extensive fusion of egg chambers and stalk cells are rare or absent.

The concentration of circulating hemocytes in mutant larvae and the distribution of the different blood cell types is not different from that of controls.

hop25/hop32 females can have eyes that are smaller in the dorso-ventral axis with significantly fewer ommatidia compared to wild-type. Ommatidia are arranged irregularly and duplicated bristles are seen. hop25/hop32 females with an eyeless phenotype with a concomitant duplication of the antenna can also be seen.

50% viable in transheterozygous combination with hop25.

Paternal rescue of the maternal effect. Germline clone analysis demonstrates that embryos have one abdominal segment missing and A4 appears wider than wild type, and partial or complete fusion of T1 and T2.

Statement
Reference

The penetrance of the ectopic wing vein phenotype seen in hop25/hop32 animals (98%) is decreased by Df(2R)CA53/+ (46%) or Df(2R)NCX10/+ (58%), but is not significantly decreased by Df(2R)Drlrv18/+ (87%).

Viability of hop25/hop32 flies is reduced if the flies also carry osupd-4.
