A 3' splice site mutation: the invariant AG dinucleotide at the 3' splice site before exon 5 is mutated to AA, abolishing the reading frame from the middle of the catalytic domain.

G?A
G to A nucleotide change in the splice acceptor site.
Mmp2W307stop/Mmp2218 transheterozygotes exhibit a decrease in lifespan compared to controls.
Mmp2W307stop/Mmp2218 is an enhancer of partially lethal - majority die | larval stage phenotype of Mmp1Q112stop/Mmp12
The larval lethality due to Mmp1Q112stop/Mmp12 is enhanced by Mmp2218/Mmp2W307stop from 84% survival to 3rd instar and 7% pupariating to 54% survival to 3rd instar and 4% pupariating.
Mmp2W307stop/Mmp2218 is partially rescued by Mmp2GPI.EGFP
Mmp2GPI.T:Avic\GFP-EGFP completely rescues the pupal lethality of Mmp2 mutants. It does not rescue the lifespan, fertility and follicle cell defects of Mmp2W307stop/Mmp2218 flies.
