The invention provides methods and compositions for modulating the expression, processing, post-translational modification, and/or activity of XBP-1 protein, or a protein in a signal transduction pathway involving XBP-1. Exemplary XBP-1 activities that can be modulated using the methods and compositions of the invention include: the Unfolded Protein Response (UPR), plasma cell differentiation, immunoglobulin production, apoptosis and the production of IL-6. The present invention also pertains to methods for identifying compounds that modulate the expression, processing, post-translational modification, and/or activity of XBP-1 protein or a molecule in a signal transduction pathway involving XBP-1. |
