title = "Post-translational modification profiling-functional proteomics for the analysis of immune regulation",
abstract = "Posttranslational modifications (PTMs) of proteins are an integral part of major cellular regulatory mechanisms dictating protein function, localization, and stability. The capacity to screen PTMs using protein microarrays has advanced our ability to identify their targets and regulatory role. This chapter discusses a unique procedure that combines functional extract-based activity assay with large-scale screening utilities of protein microarrays. This “PTM-profiling” system offers advantages in quantitatively identifying modifications in an unbiased manner in the context of specific cellular conditions. While the possibilities of studying PTMs in different settings are enormous, the immune system presents an attractive model for studying the effects of perturbations in PTMs, and specifically the ubiquitin system, as these were already implicated in both immune function and dysfunction. This chapter discusses the significance of PTM profiling in addressing basic questions in immunology. We describe detailed protocols for the preparation of functional cell extracts from immune cell cultures, following differentiation or induced signals, and screening PTMs on protein arrays, as well as basic guidelines for data analysis and interpretation.",
