[ 11 12 13 14 ] . Kidney transplants between normal and transgenic Tg26 siblings suggested that specific HIV-1 proteins within the kidney, and not circulating factors, transform infected renal epithelium [ 13 ] . Indeed, HIV-1 transgenic mice generated with an HIV-1 proviral construct mutated in the Nef "PXXP" SH3-binding motif for Src-family kinases failed to develop nephropathy [ 31 ] , and a recent in vitro analysis of podocytes infected with single gene mutants of HIV-1 further suggest that Nef plays a central role in causing the proliferative phenotype in HIVAN [ 8 ] . Utilizing these same single gene mutant viruses, we showed here that Nef appears to be play a role in the up-regulation of cyclin D 1 by HIV-1 in vitro . Importantly, these single gene mutants do not exclude the possibility that other HIV-1 gene(s) may cooperate with nef to induce cyclin D1, particularly
The adaptor protein Cas has several domains that are important for its function, an SH3 domain, a central substrate domain with up to 15 tyrosines that can serve as tyrosine kinase substrates for upstream kinases such as Src and Abl [ 19 42 43 ] , and a C-terminal Src binding domain with PXXP motifs for binding to the SH3 domain of Src, and two tyrosines providing docking sites for the Src SH2 domain upon phosphorylation [ 6 ] . The substrate domain of Cas has two major types of tyrosine motifs that can be phosphorylated and bind downstream effectors, YQXP (4 copies) and YDXP motifs (9 copies), suggesting that at least two classes of downstream effectors, one capable of binding to YDXP motifs and the other capable of binding to YQXP motifs, are assembled by this adaptor protein.
