 AB    Productive infection with HIV-1, the virus responsible for AIDS,
       requires the involvement of host cell factors for completion of the
       replicative cycle, but the identification of these factors and
       elucidation of their specific functions has been difficult. A human
       cDNA, TRBP, was recently cloned and characterized as a positive
       regulator of gene expression that binds to the TAR region of the HIV-1
       genome. Here we demonstrate that this factor is encoded by a gene,
       TARBP2, that maps to human chromosome 12 and mouse chromosome 15, and we
       also identify and map one human pseudogene (TARBP2P) and two mouse
       TRBP-related sequences (Tarbp2-rs1, Tarbp2-rs2). The map location of the
       expressed gene identifies it as a candidate for the previously
       identified factor encoded on human chromosome 12 that has been shown to
       be important for expression of HIV-1 genes. Western blotting indicates
       that despite high sequence conservation in human and mouse, the TARBP2
       protein differs in apparent size in primate and rodent cells.
