2973bp deletion within Ocrl.
A 2974 bp deletion resulting from the imprecise excision of P{EPgy2}OcrlEY15890 reported at X:1 ,817,066..1,820,039 in R5 coordinates.
OcrlΔ4 larvae show a dramatic increase in the number of circulating hemocytes compared to controls and frequently display large melanotic masses in their posterior body cavity.
OcrlΔ4 is rescued by OcrlUAS.GFP/Scer\GAL4He.PZ
The dramatic increase in the number of circulating hemocytes observed in OcrlΔ4 mutant larvae can be rescued by Scer\GAL4He.PZ-driven expression of OcrlScer\UAS.T:Avic\GFP.
