Triple point mutation in the RAM domain (amino acid replacements W1776L, F1777L and P1778A), which mutates the Su(H) protein binding sites.
NRam*.UAS/Scer\GAL4sca-537.4 partially rescues N55e11
N55e11 mutant embryos expressing NRam*.Scer\UAS under the control of Scer\GAL4sca-537.4 show residual neural hyperplasia.
Carried in a plasmid and transfected into S2 cells to study protein-protein interactions between Su(H) and N.
