HIV protein: Tat
Interaction type: downregulates
Description: HIV-1 Tat and methamphetamine downregulates beta-catenin signaling and also suppresses expression of LEF-1, a key partner of beta-catenin to regulate cognate gene expression

HIV protein: Tat
Interaction type: downregulates
Description: HIV-1 Tat-mediated downregulation of beta-catenin/Wnt signaling is dependent on the core and cysteine-rich domains of Tat. Clade C Tat lacks a dicysteine motif (C30C31) and does not downregulate beta-catenin signaling
