CD2BP2 Products

CD2BP2 is an intracellular protein which binds to a site containing two PPPGHR segments within the cytoplasmic region of CD2. Mutagenesis and NMR analysis demonstrated that the CD2 binding region of CD2BP2 includes a 17 amino acid motif also found in several yeast and Caenorhabditis elegans proteins of unknown function. In Jurkat T cells, over expression of the isolated CD2BP2 domain binding to CD2 enhances the production of interleukin 2 on crosslinking of CD2 but not the T cell receptor.
