Description
ROBLD3, also known as MAPBPIP, belongs to the GAMAD family. It is an adapter protein that enhances the efficiency of the MAP kinase cascade and facilitates the activation of MAPK2. ROBLD3 compels the recruitment of MP1 to late endosomes where they form a very stable heterodimeric complex required for ERK activation on endosomes. Recombinant human ROBLD3 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques
