cDNA cloning of a novel 85 kd protein that has SH2 domains and regulates binding of PI3-kinase to the PDGF beta-receptor.

abstract：:Temperature-sensitive mutants of vesicular stomatitis virus (VSV) belonging to complementation group III contain a lesion in the matrix (M) protein. This results in a 2--5 fold increase in transcription at the nonpermissive temperature. Co-infection of cells with one of these mutants and wild-type virus reverses this ...
