No mutation has been identified in the coding region, suggesting that this is a regulatory mutation.
raw2 mutant embryos exhibit severe cuticle defects, with dorsalized embryos.
The dorsal cuticle is reduced in homozygous embryos and the embryos have upturned tails and curved abdomens. Elongated neuronal cell bodies, thickened axon bundles and fasciculation defects are seen in the peripheral nervous system.
raw2 has lethal phenotype, non-suppressible by acal[+]/lncRNA:acal5
raw2 has majority die during embryonic stage phenotype, non-suppressible by acal[+]/lncRNA:acal5

raw2 is an enhancer of lethal phenotype of lncRNA:acal5
raw2 is an enhancer of some die during embryonic stage phenotype of lncRNA:acal5
raw2 has embryonic/larval cuticle phenotype, suppressible | partially by lncRNA:acalUAS.cRa/Scer\GAL469B
raw2 has embryonic/larval cuticle phenotype, non-suppressible by acal[+]/lncRNA:acal5
raw2 has embryonic/larval cuticle phenotype, non-suppressible by lncRNA:acal5/lncRNA:acal5
One copy of raw2 enhances the embryonic lethality seen in homozygous acal5 mutants, with a quarter of embryos phenocopying the dorsalized phenotype seen in raw2 alone. acal5 does not enhance the homozygous raw2 phenotype.
Expression of acalScer\UAS.cRa under the control of Scer\GAL469B partially suppresses the cuticle dorsalization phenotype seen in raw2 mutant embryos.
