Generation of T lymphocytes in the thymus is guided by signal transduction from the T cell receptor (TCR), but the underlying mechanism is incompletely understood. Here we have identified a Golgi-associated factor, TRAF3-interacting protein 3 (TRAF3IP3), as a crucial mediator of thymocyte development. TRAF3IP3 deficiency in mice attenuates the generation of mature thymocytes caused by impaired thymocyte-positive selection. TRAF3IP3 mediates TCR-stimulated activation of the mitogen-activated protein kinase (MAPK) extracellular signal-regulated kinase (ERK) and its upstream kinase mitogen/extracellular signal-regulated kinase (MEK). Interestingly, TRAF3IP3 exerts this signaling function through recruiting MEK to the Golgi and, thereby, facilitating the interaction of MEK with its activator BRAF. Transgenic expression of a constitutively active MEK rescues the T cell development block in Traf3ip3 knockout mice. These findings establish TRAF3IP3 as a novel regulator of T cell development and suggest a Golgi-specific ERK signaling mechanism that regulates thymocyte development.

Non-profit plasmid repository dedicated to helping scientists around the world share high-quality plasmids. Facilitates archiving and distributing DNA-based research reagents and associated data to scientists worldwide. Repository contains over 65,000 plasmids, including special collections on CRISPR, fluorescent proteins, and ready-to-use viral preparations. There is no cost for scientists to deposit plasmids, which saves time and money associated with shipping plasmids themselves. All plasmids are fully sequenced for validation and sequencing data is openly available. We handle the appropriate Material Transfer Agreements (MTA) with institutions, facilitating open exchange and offering intellectual property and liability protection for depositing scientists. Furthermore, we curate free educational resources for the scientific community including a blog, eBooks, video protocols, and detailed molecular biology resources.
