UASt regulates expression of amino acids 163-271 of Hsap\HOXA9.
The expression of Hsap\HOXA9ΔNT.UAS under the control of Scer\GAL4ey.PH leads to a small eye phenotype.
Larvae expressing Hsap\HOXA9ΔNT.UAS under the control of Scer\GAL4Hml.Δ do not show lymph gland enlargement or increased cell number, lymph gland primary lobe disruption or posterior signaling center overgrowth, but show a moderate increase in circulating hemocytes.
