TRAF3IP1: Proteins and Enzymes

MIP-T3 (microtubule-interacting protein associated with TRAF3) was originally identified in a yeast-two hybrid screen for proteins that interact with the tumor necrosis factor receptor (TNFR)-associated factor 3 (TRAF3). As a microtubule binding protein, MIP-T3 has been found to mediate the binding of DISC1 (disrupted-in-schizophrenia 1) to microtubules. MIP-T3 has also been shown to associate with IL13 receptor alpha (IL-13Ralpha1) and function as an inhibitor of IL-13 signaling. Recently, studies of the C. elegans homolog of MIP-T3 (DYF-11) have revealed that MIP-T3 is critical to cilium development; and in mammalian cells, MIP-T3 has been found to localize to basal bodies and cilia. Alternate names for MIP-T3 include TRAF3IP1, interleukin 13 receptor alpha1-binding protein 1, and TRAF3-interacting protein.
