E192K
Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
Homozygous females are completely sterile; embryos derived from these females arrest in a metaphase-like state in cycles 1-8.
Mutant larvae undergo G2 arrest in response to ionizing radiation, as do wild type larvae (assayed by scoring mitotic cells in larval eye-antennal imaginal discs).
MCPH1Z4050/MCPH1Z0978 is partially rescued by Scer\GAL4VP16.nanos.UTR/MCPH1B.UASp
