P-element excision results in a small deletion leading to removal of the first 325 codons of the Pak3 A isoform.
1827 bp deletion resulting from the imprecise excision of P{EP}Pak3EP1191, extends from the insertion site to 974 bases beyond the ATG.
Pak327A homozygous mutant embryos exhibit head holes and defects in the dorsal surface, ranging from germband retraction failure to dorsal holes and puckers.
Pak327A has embryonic/larval cuticle phenotype, enhanceable by Pak14
