The Arg-rich RNA-binding region binds the TAR RNA. This region also mediates the nuclear localization through direct binding to KPNB1 and is involved in Tat's transfer across cell membranes (protein transduction). The same region is required for the interaction with EP300, PCAF, EIF2AK2 and KDR (By similarity).
