  • RelevanceThe MAGUK (Membrane-Associated Guanylate Kinase) family of proteins is characterized by the presence of multi-PDZ and SH3 domains, and a single region of homology to Saccharomyces cerevisiae guanylate kinase (GuK) domain. All MAGUKs studied to date localize to regions of cell-cell contact such as tight junctions in epithelial cells and synaptic junctions in neurons and are believed to be involved in the assembly of multi-protein complexes via their protein-protein interaction domains. Three novel, closely related MAGUK proteins were isolated by means of different screening assays, and named MAGI1/BAP1, MAGI2/ S-SCAM /ARIP, and SLIPR/MAGI3. MAGI1 was first identified in mouse as a protein interacting with K-RasB. Three isoforms were identified, and named MAGI1a, MAGI1b, and MAGI1c, of 1139, 1171, and 1374 amino acids respectively. The isolation of a growing number of MAGI1 binding partners, together with the determination of the subcellular and tissue distribution of the different isoforms, are paving the way towards elucidation of its function.

Thank you for your patience. Here is the clarifying explanation regarding the immunogen: The immunogenic sequence was chosen based on the mutated sequence in Q96QZ7-3 or 4 and therefore it is absent in other isoforms including isoform 1.  It is i...

Thank you for contacting us. I heard back from the lab with the following information: ab37543 can potentially recognize isoform 3 or 4. However, I am confused about this reply since the isoforms 3 and 4 (according to the UniProt database entry...
