DESCRIPTION

Also known as TIAM1_MOUSE, Tiam1, Tiam-1. Guanyl-nucleotide exchange factor that activates RHO-like proteins and connects extracellular signals to cytoskeletal activities. Activates RAC1, CDC42, and to a lesser extent RHOA and their downstream signaling to regulate processes like cell adhesion and cell migration. Component of the Par polarity complex, composed of at least phosphorylated PRKCZ, PARD3 and TIAM1 (By similarity). Interacts with BAIAP2. Interacts (via PDZ domain) with CNTNAP4, SDC1 and SDC3 (via C-terminus) (By similarity). Interacts with CD44, PARD3 and MAPK8IP2. Interacts with EPHA8; regulates clathrin-mediated endocytosis of EPHA8. Interacts with NTRK2; mediates the activation of RAC1 by BDNF.
