Functions as a RAC1 guanine nucleotide exchange factor (GEF), activating Rac proteins by exchanging bound GDP for free GTP. Additionally we are shipping DEP Domain Containing 2 Proteins (4) and DEP Domain Containing 2 Kits (3) and many more products for this protein.
Showing 8 out of 8 products:
findings identify PREX2 as a mediator of NRAS (show NRAS Antibodies)-mutant melanoma development that acts through the PI3K (show PIK3CA Antibodies)/PTEN (show PTEN Antibodies)/Akt (show AKT1 Antibodies) pathway to regulate gene expression of a cell cycle regulator (show CDKN2A Antibodies)
second messengers activate the Rac1 signal, which sets in motion a cascade whereby PAKs phosphorylate and negatively regulate PREX2 to decrease Rac1 activation.
PREX2 mutants are likely selected in cancer to escape PTEN (show PTEN Antibodies)-mediated inhibition of invasion.
CXCL9 (show CXCL9 Antibodies) is involved in the invasion ability of hepatocellular carcinoma cells possibly through up-regulation of its potential effector PREX2.
Results demonstrate that miR (show MLXIP Antibodies)-338-3p affects gastric cancer progression through PTEN (show PTEN Antibodies)-AKT (show AKT1 Antibodies) signaling by targeting P-Rex2a in gastric cancer cells
P-REX2 PH-domain-mediated inhibition of PTEN (show PTEN Antibodies) has a role in regulating insulin (show INS Antibodies) sensitivity and glucose homeostasis
MiR (show MLXIP Antibodies)-338-3p affects the PTEN (show PTEN Antibodies)/Akt (show AKT1 Antibodies) pathway by down-regulating PREX2a.
Studies indicate relevance of P-Rex1 (show PREX1 Antibodies) and P-Rex2a, in breast tumorigenesis, and suggest that the exchange factors Vav2 (show VAV2 Antibodies) and Vav3 (show VAV3 Antibodies) play synergistic roles in breast cancer by sustaining tumor growth, neoangiogenesis, and metastasis.
Analysis of whole-genome sequence data identified PREX2 (phosphatidylinositol-3,4,5-trisphosphate-dependent Rac exchange factor 2)--a PTEN (show PTEN Antibodies)-interacting protein and negative regulator of PTEN (show PTEN Antibodies) in breast cancer--as a significantly mutated gene with a mutation frequency of approximately 14% in an independent extension cohort of 107 human melanomas
suggests that aberrant control of PTEN (show PTEN Antibodies) by P-REX2a may represent a key tumorigenic mechanism, in agreement with recent studies supporting the pathological relevance of several other proposed PTEN (show PTEN Antibodies) regulators
This study demonistrated that the P-Rex2, a GEF (show ARHGEF2 Antibodies) that specifically activates Rac (show AKT1 Antibodies) small GTPases, is expressed in a cell- and synapse-specific manner in the retina.
PI3K/P-Rex/Rac (show AKT1 Antibodies) pathway is required for late phase long-term potentiation in the mouse cerebellum
P-Rex1 (show PREX1 Antibodies) and P-Rex2 are important regulators of Purkinje cell morphology and cerebellar function
Functions as a RAC1 guanine nucleotide exchange factor (GEF), activating Rac proteins by exchanging bound GDP for free GTP. Its activity is synergistically activated by phosphatidylinositol 3,4,5-trisphosphate and the beta gamma subunits of heterotrimeric G protein. Mediates the activation of RAC1 in a PI3K-dependent manner. May be an important mediator of Rac signaling, acting directly downstream of both G protein- coupled receptors and phosphoinositide 3-kinase (By similarity).
