Summary: Enables beta-catenin binding activity and glutamate receptor binding activity. Involved in habituation; long-term memory; and regulation of protein localization. Located in adherens junction and synapse. Is expressed in several structures, including anus; egg-laying apparatus; intestine; neurons; and pharynx. Human ortholog(s) of this gene implicated in nephrotic syndrome type 15. Orthologous to several human genes including MAGI3 (membrane associated guanylate kinase, WW and PDZ domain containing 3).

What's a GeneRIF?

study demonstrates novel physical interactions between MAGI-1, AFD-1/afadin and SAX-7/L1CAM, which are part of a functional interactome that includes components of the core cadherin-catenin complex; results suggest MAGI-1 helps to partition and maintain a stable, spatially ordered apical junction during morphogenesis
Title: A genome-wide functional screen shows MAGI-1 is an L1CAM-dependent stabilizer of apical junctions in C. elegans.
MAGI-1 functions as an "organizer" that ensures the correct segregation of different cell adhesion complexes into distinct domains along the lateral plasma membrane.
Title: The C. elegans MAGI-1 protein is a novel component of cell junctions that is required for junctional compartmentalization.
MAGI-1 has a role in neuron-specific regulation of associative learning and memory in C. elegans
Title: Neuron-specific regulation of associative learning and memory by MAGI-1 in C. elegans.
MAGI-1L interacts with AMPARs through the intracellular domain of the GLR-2 subunit, which is required for the modulation of AMPAR synaptic localization by mechanical stimulation.
Title: MAGI-1 modulates AMPA receptor synaptic localization and behavioral plasticity in response to prior experience.
