T-cell lymphoma invasion and metastasis-inducing protein 1

Rho guanine nucleotide exchange factor TIAM1 is a protein that in humans is encoded by the TIAM1 gene.

Structure
TIAM1 is tightly associate with BAIAP2 as a subunit. It contains one DH (DBL-homology) domain, one PDZ domain, two PH domains and one Ras-binding RBD domain. == Function ==
Function
TIAM1 modulates the activity of Rho GTP-binding proteins and connects extracellular signals to cytoskeletal activities. In addition, TIAM1 activates Rac1, CDC42, and to a lesser extent RhoA. == Clinical significance ==
Clinical significance
TIAM1 is found in virtually all tumor cell lines examined including B- and T-lymphomas, neuroblastomas, melanomas and carcinomas. == Interactions ==
Interactions
T-cell lymphoma invasion and metastasis-inducing protein 1 has been shown to interact with ANK1, Myc, RAC1 and PPP1R9B. Tiam1 interacts also with para-cingulin, that plays a role in recruiting Tiam1 to junctions and thus activate Rac1 at epithelial junctions. == References ==
