This disclosure provides anti-human cytomegalovirus antibodies and methods of treatment, prophylaxis, detection, and diagnosis using the same. In another aspect, the disclosure features therapeutic, prophylactic, and/or diagnostic compositions for human cytomegalovirus infection or for a human cytomegalovirus-related disease that include a binding agent (e.g., antibody) or polynucleotide disclosed herein. In some embodiments, the composition is formulated for ocular or topical administration. The compositions can further include one or more human cytomegalovirus-neutralizing antibodies, an intravenous immunoglobulin preparation, and/or one or more antiviral compounds (e.g., ganciclovir, foscamet, cidofovir, or valganciclovir).

The invention relates to antibody reagents that specifically bind to peptides carrying a ubiquitin remnant from a digested or chemically treated biological sample. The reagents allow the technician to identify ubiquitinated polypeptides as well as the sites of ubiquitination on them. The reagents are preferably employed in proteomic analysis using mass spectrometry. The antibody reagents specifically bind to the remnant of ubiquitin (i.e., a diglycine modified epsilon amine of lysine) left on a peptide which as been generated by digesting or chemically treating ubiquitinated proteins. The inventive antibody reagents affinity to the ubiquitin remnant does not depend on the remaining amino acid sequences flanking the modified (i.e., ubiquitinated) lysine, i.e., they are context independent.

The invention provides methods to identify, diagnose, and treat kidney cancer through the detection of expression and/or activity of anaplastic lymphoma kinase (ALK). The detection of the presence of a polypeptide with ALK kinase activity (e.g., by detecting expression and/or activity of the polypeptide), identify those kidney cancers that are likely to respond to an ALK-inhibiting therapeutic.

The present invention relates to methods of classifying cancer cells based on the presence, absence or level of tyrosine kinase or a phophorylated tyrosine kinase. The present invention also related to methods of treating cancer using cancer classification. The present invention further related to methods of determining the effectiveness of a treatment for cancer using cancer classification.

In accordance with the invention, a novel gene translocation, (4p15, 6q22), in human non-small cell lung carcinoma (NSCLC) that results in a fusion proteins combining part of Sodium-dependent Phosphate Transporter Isoform NaPi-3b protein (SLC34A2) with Proto-oncogene Tyrosine Protein Kinase ROS Precursor (ROS) kinase has now been identified. The SLC34A2-ROS fusion protein is anticipated to drive the proliferation and survival of a subgroup of NSCLC tumors. The invention therefore provides, in part, isolated polynucleotides and vectors encoding the disclosed mutant ROS kinase polypeptides, probes for detecting it, isolated mutant polypeptides, recombinant polypeptides, and reagents for detecting the fusion and truncated polypeptides. The disclosed identification of the new fusion protein enables new methods for determining the presence of these mutant ROS kinase polypeptides in a biological sample, methods for screening for compounds that inhibit the proteins, and methods for inhibiting the progression of a cancer characterized by the mutant polynucleotides or polypeptides, which are also provided by the invention.
