Rho guanine nucleotide exchange factor TIAM1 is a protein that in humans is encoded by the TIAM1 gene. [4] [5] [6]
Rho guanine nucleotide exchange factor TIAM1 is a protein that in humans is encoded by the TIAM1 gene. [4] [5] [6]
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.
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.
TIAM1 is found in virtually all tumor cell lines examined including B- and T-lymphomas, neuroblastomas, melanomas and carcinomas.
T-cell lymphoma invasion and metastasis-inducing protein 1 has been shown to interact with ANK1, [7] Myc, [8] RAC1 [9] [10] and PPP1R9B. [11]
Tiam1 interacts also with para-cingulin, that plays a role in recruiting Tiam1 to junctions and thus activate Rac1 at epithelial junctions. [12]
Cell division control protein 42 homolog is a protein that in humans is encoded by the CDC42 gene. Cdc42 is involved in regulation of the cell cycle. It was originally identified in S. cerevisiae (yeast) as a mediator of cell division, and is now known to influence a variety of signaling events and cellular processes in a variety of organisms from yeast to mammals.
Rac1, also known as Ras-related C3 botulinum toxin substrate 1, is a protein found in human cells. It is encoded by the RAC1 gene. This gene can produce a variety of alternatively spliced versions of the Rac1 protein, which appear to carry out different functions.
Transforming protein RhoA, also known as Ras homolog family member A (RhoA), is a small GTPase protein in the Rho family of GTPases that in humans is encoded by the RHOA gene. While the effects of RhoA activity are not all well known, it is primarily associated with cytoskeleton regulation, mostly actin stress fibers formation and actomyosin contractility. It acts upon several effectors. Among them, ROCK1 and DIAPH1 are the best described. RhoA, and the other Rho GTPases, are part of a larger family of related proteins known as the Ras superfamily, a family of proteins involved in the regulation and timing of cell division. RhoA is one of the oldest Rho GTPases, with homologues present in the genomes since 1.5 billion years. As a consequence, RhoA is somehow involved in many cellular processes which emerged throughout evolution. RhoA specifically is regarded as a prominent regulatory factor in other functions such as the regulation of cytoskeletal dynamics, transcription, cell cycle progression and cell transformation.
Ras-related C3 botulinum toxin substrate 3 (Rac3) is a G protein that in humans is encoded by the RAC3 gene. It is an important component of intracellular signalling pathways. Rac3 is a member of the Rac subfamily of the Rho family of small G proteins. Members of this superfamily appear to regulate a diverse array of cellular events, including the control of cell growth, cytoskeletal reorganization, and the activation of protein kinases.
Rho guanine nucleotide exchange factor 7 is a protein that in humans is encoded by the ARHGEF7 gene.
A-kinase anchor protein 13 is a protein that in humans, is encoded by the AKAP13 gene. This protein is also called AKAP-Lbc because it encodes the lymphocyte blast crisis (Lbc) oncogene, and ARHGEF13/RhoGEF13 because it contains a guanine nucleotide exchange factor (GEF) domain for the RhoA small GTP-binding protein.
Rho guanine nucleotide exchange factor 6 is a protein that, in humans, is encoded by the ARHGEF6 gene.
Plexin B1 is a protein of the plexin family that in humans is encoded by the PLXNB1 gene.
Rho guanine nucleotide exchange factor 1 is a protein that in humans is encoded by the ARHGEF1 gene. This protein is also called RhoGEF1 or p115-RhoGEF.
Rho guanine nucleotide exchange factor 2 is a protein that in humans is encoded by the ARHGEF2 gene.
Rho guanine nucleotide exchange factor 11 is a protein that in humans is encoded by the ARHGEF11 gene. This protein is also called RhoGEF11 or PDZ-RhoGEF.
Rho guanine nucleotide exchange factor 12 is a protein that in humans is encoded by the ARHGEF12 gene. This protein is also called RhoGEF12 or Leukemia-associated Rho guanine nucleotide exchange factor (LARG).
RhoG is a small monomeric GTP-binding protein, and is an important component of many intracellular signalling pathways. It is a member of the Rac subfamily of the Rho family of small G proteins and is encoded by the gene RHOG.
Triple functional domain protein is a protein that in humans is encoded by the TRIO gene.
Neurabin-2 is a protein that in humans is encoded by the PPP1R9B gene.
Guanine nucleotide exchange factor VAV3 is a protein that in humans is encoded by the VAV3 gene.
Guanine nucleotide exchange factor DBS is a protein that in humans is encoded by the MCF2L gene.
Guanine nucleotide-binding protein subunit alpha-13 is a protein that in humans is encoded by the GNA13 gene.
Cingulin-like protein 1, also known as paracingulin or junction-associated-coiled-coil protein (JACOP), is a protein which is encoded by the CGNL1 gene.
Pleckstrin homology domain containing, family G member 2 (PLEKHG2) is a protein that in humans is encoded by the PLEKHG2 gene. It is sometimes written as ARHGEF42, FLJ00018.
