Breakpoint in the coding region of gpp.
gppXXV weakly suppresses 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-w#11}16 and P{Mcp-w#11}102 in cis but does not suppress the pairing-sensitive silencing seen in flies carrying P{Mcp-wy#2}63 and P{Mcp-ff#15}30 in cis.
