N-methyl-d-aspartate receptors (NMDA receptors) play critical roles in brain functions and diseases. The expression, trafficking, synaptic location and function of different NMDA receptor subtypes are not static, but regulated dynamically in a cell-specific and synapse-specific manner during physiological and pathological conditions. In this review, we will examine recent evidence on the post-translational modulation of NMDA receptors subunit, in particular GluN2B subunit, such as phosphorylation, palmitoylation, and ubiquitination. In parallel, we will overview the roles of these modifications of GluN2B-NMDA receptor subtype in physiological functions, such as learning and memory, and pathophysiological conditions, such as chronic pain, ischemia and neurodegenerative diseases.
