Nucleotide change:

T9248645C

Amino acid change:

F72L | Dsor1-PA; F69L | Dsor1-PB

Comment:

Analogous mutation in human MEK1 implicated in RAS-related diseases; mutation carried on in vitro construct; site of nucleotide substitution in fly gene inferred by FlyBase curator based on reported amino acid change. F53 in human MEK1 aligns with F72 in Drosophila ortholog Dsor1.
