In cher1 mutants, egg chamber ring canals lack the robust F-actin cytoskeleton found in wild type controls.
cher1 heterozygotes do not exhibit a significant change in the number of recognizable sarcomeres in adult indirect flight muscles, as compared to controls. cher1/Df(3R)Exel6176 transheterozygotes exhibit widening of Z-discs at the adult indirect flight muscle sarcomeres, as compared to controls.
cher1 homozygous embryos display increased frequency of defasciculation defects in axons of the intersegmental nerve b, segmental nerve as well as intersegmental nerve (no obvious defects in the morphology and development of ventrolateral muscles are observed).
Homozygous embryos show defects in the guidance of the intersegmental nerve in the periphery.
Homozygous larvae have lamellocytes in the circulation without any immune challenge (in contrast to wild-type controls). The number of these cells in the circulation is further increased following infestation with a parasitoid wasp.
Egg chambers of homozygous females have impaired cytoplasm transport from nurse cell to oocyte. The egg chamber phenotype of cher1 homozygotes is less severe than that of cher1 homozygotes. Homozygous egg chambers lack the actin inner rim of the ring canals, although subcortical actin appears normal. The fusomes ares normal in the early germaria and develop into normal branched polyfusomes.
Defective in cytoplasm transport.

Loss of cher markedly interferes with the growth of Ras85DV12.Scer\UAS scrib1 tumours. The loss of cher does not affect the level of apoptosis in either the clonal nor the surrounding eye-antennal imaginal disc, indicating that loss of cher does not affect tumour cell viability.
Eye-antennal imaginal discs carrying Ras85DV12.Scer\UAS scrib1 cher1 clones display extra cell divisions, mainly occurring in the surrounding non-clonal tissue.
