HIV protein: Tat
Interaction type: binds
Description: Using a yeast two-hybrid system, the splicing factor SF2-associated protein p32 has been shown to bind to the basic domain of HIV-1 Tat (amino acids 47-59), suggesting a role for p32 in mediating the biological activity of Tat during HIV-1 replication
