Deletion that removes the linker region of the Cp190 protein (deletion of part of exon 2) while preserving the reading frame of the remaining coding sequence.
Neuroblasts in Cp190ΔL/Df(3R)E(mod)4-1P11 flies display DNA condensation defects, abnormally curved mitotic spindles, and centrosome detachment from the spindle following spindle formation.
