HIV protein: Rev
Interaction type: requires
Description: In stable Sam68 knockdown HeLa cells, HIV-1 Rev activation of RRE-mediated gene expression and HIV-1 production are inhibited due to the failure of exporting unspliced HIV-1 mRNAs to the cytoplasm, indicating Rev requires Sam68 for proper function
