Reagents for the detection of protein phosphorylation in anaplastic large cell lymphoma signaling pathways
First Claim
1. An isolated phosphorylation site-specific antibody that specifically binds a human Anaplastic Large Cell Lymphoma (ALCL)-related signaling protein, wherein said signaling protein is prohibitin D, only when said signaling protein is phosphorylated at the tyrosine at position 128, comprised within the phosphorylatable peptide sequence listed in SEQ ID NO:
- 40, wherein said antibody does not bind said signaling protein when not phosphorylated at said tyrosine.

Abstract
The invention discloses 211 novel phosphorylation sites identified in signal transduction proteins and pathways underlying Anaplastic Large Cell Lymphoma (ALCL) involving the ALK-NPM translocation/fusion, and provides phosphorylation-site specific antibodies and heavy-isotope labeled peptides (AQUA peptides) for the selective detection and quantification of these phosphorylated sites/proteins, as well as methods of using the reagents for such purpose. Among the phosphorylation sites identified are sites occurring in the following protein types: Protein Kinases (including Receptor Tyrosine Kinases), Adaptor/Scaffold Proteins, Cellular Metabolism or Miscellaneous Enzymes, Oxidoreductases, Transcription Factors, Cytoskeletal Proteins, Translation Initiation Complexes, RNA Binding Proteins, Proteases, Acetyltransferases, G protein regulators/GTPases, Helicases, Apoptosis/Cell Cycle Regulation proteins, and Hydrolases.
