    • The present invention is based on a family of membrane proteins, Phospholipid Scramblases (PLSCR), that mediate accelerated trans-bilayer movement of plasma membrane phospholipids in response to elevated cytoplasmic calcium. At least one Phospholipid Scramblase gene is highly inducible by interferon. Interferon-induced expression of Phospholipid Scramblase 1 (and/or related genes) alters the physical and functional properties of the cell surface so as to (1) inhibit tumor cell proliferation and survival; (2) inhibit maturation and release of membrane-enveloped viruses; and/or (3) promote clearance of virus-infected cells and cancer cells through the reticuloendothelial system. The present invention provides Phospholipid Scramblase polypeptides, polynucleotide sequences that encode Phospholipid Scramblase polypeptides, and antibodies that are immunoreactive with the polypeptides. The finding that human Phospholipid Scramblase 1 polypeptides are induced by interferons, indicates a role for the Scramblase polypeptides in treating and preventing cancer and viral infection.

    • Isolated 2-5A-dependent RNases, an interferon-induced enzyme which is activated by 5'-phosphorylated, 2',5'-linked oligoadenylates (2-5A) and implicated in both the molecular mechanisms of interferon action and in the fundamental control of RNA stability in mammalian cells, and encoding sequences therefor are disclosed. The expression cloning and analysis of murine and human 2-5A-dependent RNases is also disclosed. Recombinant human 2-5A-dependent RNase produced in vitro bound an activating affinity matrix, 2-5A-cellulose, resulting in ribonuclease activity. The 2-5A binding properties of the recombinant and naturally occurring forms of 2-5A-dependent RNase are basically identical. Interferon induction of 2-5A-dependent RNase expression is demonstrated by measuring the mRNA levels in cells treated with interferon and cycloheximide. Analysis of aligned murine and human 2-5A-dependent RNase sequences revealed several features, including similarity to RNase E which is implicated in the control of mRNA stability in E. coli. A duplicated phosphate-binding loop motif is determined by deletion analysis and site-directed mutagenesis to function in the binding of 2-5A.
