Table 1. Yeast two-hybrid assay.

DNA binding fusion   Transcriptional activation fusion   Units of β-galactosidase
FOXP3ΔFKH clone (LCK) 3.08
FOXP3ΔFKH Non-reactive clone 0.34
Positive control 10.0
Negative control 0.53

One of the positive clones resulting from screening with Foxp3 ∆FKH (1-332 amino acids) as a bait was identified as encoding a portion of LCK.
