UAS regulates expression of Hsap\TARDBP containing a T199A replacement, preventing O-GlcNAcylation at this site and thereby reducing overall O-GlcNAcylation of the protein.
The expression of Hsap\TARDBPT199A.UAS under the control of Scer\GAL4elav-C155 leads to decreased third instar larval crawling ability and decreased adult climbing ability.
