Target Data

Function Modulates the activity of RHO-like proteins and connects extracellular signals to cytoskeletal activities. Acts as a GDP-dissociation stimulator protein that stimulates the GDP-GTP exchange activity of RHO-like GTPases and activates them. Activates RAC1, CDC42, and to a lesser extent RHOA. Required for normal cell adhesion and cell migration.
Gene References into Functions
  1. Study in hepatocellular carcinoma (HCC) cells proves that SETDB1 promotes the proliferation and migration of cells by forming SETDB1-Tiam1 compounds. SETDB1-Tiam1 compounds were involved in a novel pathway, which regulated epigenetic modification of gene expression in HCC patients samples. PMID: 29739365

The effects of Tiam1 on metastasis and EMT mediated by the Wnt/beta-catenin pathway were reversed by Rac1 silencing, suggesting that the prometastatic effect of Tiam1 is mediated by the activation of Rac1.
