Frameshift after P165 resulting in a truncated (171 aa) protein, lacking the nuclear localisation site and zinc finger domains.
Location of unspecified frameshift event (after P165 of ush-PA), which results in a truncated protein.
lamellocyte (with ushrev24)
ushVX22/+ third instar larval lymph glands exhibit hyperplasia, and the lymph glands are on average twice the size of wildtype glands. Plasmatocyte and crystal cell numbers are substantially increased in ushVX22/+ lymph glands. Only a marginal increase in lamellocyte differentiation is observed.
ushVX22/ushrev24 third instar larval lymph glands exhibit hyperplasia. Lymph glands are on average two times larger in size compared to ushVX22/+ larvae, and three times larger in size compared to wildtype controls. Plasmatocyte and crystal cell numbers are decreased in ushVX22/ushrev24 lymph glands. A substantial increase in lamellocyte differentiation is observed.
Lymph glands from ushVX22/ushrev24 second instar larvae have a comparable size to control glands. In third instar larvae, lymph glands are extremely hypertrophic compared to controls. There is a four-fold increase in circulating haemocytes, including a large lamellocyte population which comprises about 20% of all circulating haemocytes.
The lymph glands of ushVX22/+ larvae are hypertrophic. Crystal cells are still predominantly confined to the cortical zone, but are less densely packed. Larvae have a small but significant circulating lamellocyte population, compared to a almost no lamellocytes circulating in wild-type larvae. The number of non-lamellocyte cells is much increased compared to control larvae.
Homozygous clones in the lateral part of the notum differentiate normally. Clones that extend into the scutellum fail to differentiate, producing large gaps in this region. Clones touching the dorsal midline are associated with a cleft in the thorax, and clones extending into the dorsocentral area are associated with a lack or mispositioning of the dorsocentral bristles. Dorsocentral bristles produced by wild-type cells in flies with clones in part of the dorsocentral area are also misplaced from their normal positions.

Lamellocyte production is eliminated in ushVX22/+, srp3/+ double heterozygous mutant larvae, reducing numbers to wild-type levels. The number of non-lamellocyte cells is not affected.
Lamellocyte production is drastically reduced in ushVX22/+, srpneo45/+ double heterozygous mutant larvae, but not quite to wild-type levels. The number of non-lamellocyte cells is reduced to almost half the wild-type value.
