Is there Kozak sequence present in the Human ORFeome clones?

In the reference paper for the collection it states: "The 5' Gateway primer also incorporates a Kozak consensus nucleotide, G, at -3 relative to the ATG, thereby allowing efficient translational initiation from the ATG initiation codon."
