MCF2 Polyclonal Antibody

disease:MCF2 and DBL represent two activated versions of the same proto-oncogene.,domain:The CRAL-TRIO domain is involved in interaction with inositol phospholipids.,domain:The DH domain is essential for transforming activity and directly catalyzes GDP-GTP exchange activity. It may interact with CCPG1.,function:Guanine nucleotide exchange factor (GEF) that modulates the Rho family of GTPases. Promotes the conversion of some member of the Rho family GTPase from the GDP-bound to the GTP-bound form. Isoform 1 exhibits no activity toward RHOA, RAC1 or CDC42. Isoform 2 exhibits decreased GEF activity toward CDC42. Isoform 3 exhibits a weak but significant activity toward RAC1 and CDC42. Isoform 4 exhibits significant activity toward RHOA and CDC42. The truncated DBL oncogene is active toward RHOA, RAC1 and CDC42.,similarity:Belongs to the MCF2 family.,similarity:Contains 1 CRAL-TRIO domain.,similarity:Contains 1 DH (DBL-homology) domain.,similarity:Contains 1 PH domain.,similarity:Contains 1 spectrin repeat.,subcellular location:Colocalizes with CDC42 to plasma membrane.,subunit:Interacts with an array of inositol phospholipids such as phosphatidylinositol 3-phosphate (PI3P), phosphatidylinositol 4-phosphate (PI4P) and phosphatidylinositol 5-phosphate (PI5P). May interact with CCPG1.,tissue specificity:Isoform 1 is expressed only in brain. Isoform 3 is expressed in heart, kidney, spleen, liver and testis. Isoform 4 is expressed in brain, heart, kidney, testis, placenta, stomach and peripheral blood. The protein is detectable in brain, heart, kidney, intestine, muscle, lung and testis.,
