Western blot analysis of MPP3 over-expressed 293 cell line, cotransfected with MPP3 Validated Chimera RNAi ( Cat # H00004356-R01V ) (Lane 2) or non-transfected control (Lane 1). Blot probed with MPP3 monoclonal antibody (M01), clone 4D7 (Cat # H00004356-M01 ). GAPDH ( 36.1 kDa ) used as specificity and loading control.
This gene product is a member of a family of membrane-associated proteins termed MAGUKs (membrane-associated guanylate kinase homologs). MAGUKs interact with the cytoskeleton and regulate cell proliferation, signaling pathways, and intracellular junctions. This protein contains a conserved sequence, called the SH3 (src homology 3) motif, found in several other proteins that associate with the cytoskeleton and are suspected to play important roles in signal transduction. Alternatively spliced transcript variants have been identified. One transcript variant is experimentally supported, but it doesn't encode a protein. [provided by RefSeq
