Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Size
small protein node
small nodes:

Regulates chemotaxis of BM-derived neutrophils and dendritic cells (in vitro) (By similarity) (359 aa)
TIAM1T-cell lymphoma invasion and metastasis 1; Modulates the activity of RHO-like proteins and connects extracellular signals to cytoskeletal activities.

ABRactive BCR-related (859 aa)
F2Rcoagulation factor II (thrombin) receptor; High affinity receptor for activated thrombin coupled to G proteins that stimulate phosphoinositide hydrolysis. May play a role in platelets activation and in vascular development (425 aa)
ARHGEF1Rho guanine nucleotide exchange factor (GEF) 1; Seems to play a role in the regulation of RhoA GTPase by guanine nucleotide-binding alpha-12 (GNA12) and alpha-13 (GNA13) subunits. Acts as GTPase-activating protein (GAP) for GNA12 and GNA13, and as guanine nucleotide exchange factor (GEF) for RhoA GTPase. Activated G alpha 13/GNA13 stimulates the RhoGEF activity through interaction with the RGS-like domain. This GEF activity is inhibited by binding to activated GNA12. Mediates angiotensin-2- induced RhoA activation (927 aa)
TRIOtrio Rho guanine nucleotide exchange factor; Promotes the exchange of GDP by GTP. Together with leukocyte antigen-related (LAR) protein, it could play a role in coordinating cell-matrix and cytoskeletal rearrangements necessary for cell migration and cell growth (3097 aa)
ARHGEF3Rho guanine nucleotide exchange factor (GEF) 3 (558 aa)
ARHGEF18Rho/Rac guanine nucleotide exchange factor (GEF) 18; Acts as guanine nucleotide exchange factor (GEF) for RhoA GTPases. May play a role in actin cytoskeleton reorganization in different tissues since its activation induces formation of actin stress fibers. Also act as a GEF for RAC1, inducing production of reactive oxygen species (ROS). Does not act as a GEF for CDC42. The G protein beta-gamma (Gbetagamma) subunits of heterotrimeric G proteins act as activators, explaining the integrated effects of LPA and other G-protein coupled receptor agonists on actin stress fiber formation, cell [...] (1173 aa)
CACNA1Acalcium channel, voltage-dependent, P/Q type, alpha 1A subunit (2506 aa)

ARHGEF2Rho/Rac guanine nucleotide exchange factor (GEF) 2; Activates Rho-GTPases by promoting the exchange of GDP for GTP. May be involved in epithelial barrier permeability, cell motility and polarization, dendritic spine morphology, antigen presentation, leukemic cell differentiation, cell cycle regulation, and cancer. Binds Rac-GTPases, but does not seem to promote nucleotide exchange activity toward Rac-GTPases, which was uniquely reported in PubMed-9857026. May stimulate instead the cortical activity of Rac. Inactive toward CDC42, TC10, or Ras- GTPases. Forms an intracellular sensing sys [...] (986 aa)
GBF1golgi brefeldin A resistant guanine nucleotide exchange factor 1; Promotes guanine-nucleotide exchange on ARF5. Promotes the activation of ARF5 through replacement of GDP with GTP (By similarity) (1859 aa)

ITSN1intersectin 1 (SH3 domain protein); Adapter protein that may provide indirect link between the endocytic membrane traffic and the actin assembly machinery. May regulate the formation of clathrin-coated vesicles. Involved in endocytosis of integrin beta-1 (ITGB1) and transferrin receptor (TFR); internalization of ITGB1 as DAB2-dependent cargo but not TFR may involve association with DAB2.
