Cytology
Description

The native Orc6 promoter and UASt regulatory sequences are fused upstream of a mutated form of Orc6 that contains a K23E amino acid substitution. This change is equivalent to a K23E change in the orthologous human ORC6 gene, a variant identified in a patient with Meier-Gorlin syndrome. The coding sequence is tagged at the N-terminal end with GFP.
