Applications Key: W=Western Blotting, IP=Immunoprecipitation, IF-IC=Immunofluorescence (Immunocytochemistry),

Specificity / Sensitivity

MAGI3-Akt3 Fusion Protein (D4D3P) Rabbit mAb recognizes transfected MAGI3-Akt3 fusion protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding the fusion site of MAGI3-Akt3 fusion protein.



Confocal immunofluorescent analysis of MCF 10A cells stably transfected with MAGI3/Akt3 (left) or with a control vector (right), using MAGI3-Akt3 Fusion Protein (D4D3P) Rabbit mAb (green). Actin filaments were labeled with DyLight™ 554 Phalloidin #13054 (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).

Western Blotting

Western Blotting

Western blot analysis of extracts from MCF 10A cells, mock-transfected (-) or transfected with human MAGI3/Akt3 (hMAGI3/Akt3; +), using MAGI3-Akt3 Fusion Protein (D4D3P) Rabbit mAb (upper) and β-Actin (13E5) Rabbit mAb #4970 (lower).


MAGI3-Akt3 fusion was first detected in triple-negative breast cancer tissues in a sequence analysis research study (1). Rearrangement occurs between the genes MAGI3 (membrane-associated guanylate kinase, WW and PDZ domain containing 3) on chromosome 1p and Akt3 on chromosome 1q, leading to a translocation from intron 9 in MAGI3 to intron1 of Akt3. This rearrangement yields an in-frame fusion gene that translates into a MAGI3-Akt3 fusion protein. Overexpression studies show that MAGI3-Akt3 fusion protein leads to the constitutive activation of Akt kinase (1). Further research studies demonstrate that this fusion is not a recurrent event in triple-negative breast cancer (2,3).
