Inversion breakpoint in an intron of gpp.
Homozygotes are lethal during late larval stages and show no obvious patterning defects. The growth rate of mutant larvae is reduced relative to similarly aged control larvae. Dissected gpp61A/gppX male pupae show a reduction in the number of sex comb teeth and also have sex combs on the fourth tarsal segment of the first leg.
gppX does not suppress the pairing-sensitive silencing seen in flies carrying P{Mcp-ff#13}101 and P{Mcp-w#14}AP-2stummelbein in cis or P{Mcp-wy#2}63 and P{Mcp-ff#15}30 in cis, but suppresses the pairing-sensitive silencing seen in flies carrying P{Mcp-w#11}16 and P{Mcp-w#11}102 in cis.
