microRNA-302c-3p inhibits renal cell carcinoma cell proliferation by targeting Grb2-associated binding 2 (Gab2)
The expression and biological function of Grb2-associated binding 2 (Gab2) in renal cell carcinoma (RCC) cells was tested here. We showed that Gab2 expression was significantly elevated in human RCC tissues and RCC cells. It was correlated with over-activation of Akt and downregulation of microRNA-302c-3p ("miR-302c-3p"), a putative Gab2-targeting microRNA. Knockdown of Gab2 inhibited Akt activ...
متن کاملUnderstanding the mechanism of binding between Gab2 and the C terminal SH3 domain from Grb2
Gab2 is a large disordered protein that regulates several cellular signalling pathways and is overexpressed in different forms of cancer. Because of its disordered nature, a detailed characterization of the mechanisms of recognition between Gab2 and its physiological partners is particularly difficult. Here we provide a detailed kinetic characterization of the binding reaction between Gab2 and ...
متن کاملCleavage of Grb2-Associated Binding Protein 2 by Viral Proteinase 2A during Coxsackievirus Infection
Coxsackievirus type B3 (CV-B3), an enterovirus associated with the pathogenesis of several human diseases, subverts, or employs the host intracellular signaling pathways to support effective viral infection. We have previously demonstrated that Grb2-associated binding protein 1 (GAB1), a signaling adaptor protein that serves as a platform for intracellular signaling assembly and transduction, i...
متن کاملDistinct binding modes of two epitopes in Gab2 that interact with the SH3C domain of Grb2.
Grb2 and Gab2 form a complex implicated in normal cell signaling and cancer development. Binding of the Grb2SH3C domain to Gab2 is essential for the interaction, but molecular details remained undefined. Using peptide arrays and isothermal titration calorimetry, two Grb2SH3C binding sites in Gab2 (Gab2a and Gab2b) were confirmed and characterized. Gab2a bears similarity to a p27Kip1 epitope tha...
متن کاملEffects of Grb2-associated binding protein 2-specific siRNA on the migration and invasion of MG-63 osteosarcoma cells
To investigate the association between the expression of growth factor receptor binding protein 2-associated binding protein 2 (Gab2) in human osteosarcoma as well as the effects of Gab2 on invasion and metastasis, human MG-63 osteosarcoma cells were transfected with small interfering (si)RNA plasmid. Gab2 protein and mRNA expression levels were detected using western blotting and reverse trans...
