Summary

MAGI2 (membrane associated guanylate kinase, WW and PDZ domain containing 2, HGNC:18957) is a protein-coding gene on chromosome 7q21.11, encoding Membrane-associated guanylate kinase, WW and PDZ domain-containing protein 2 (Q86UL8). Seems to act as a scaffold molecule at synaptic junctions by assembling neurotransmitter receptors and cell adhesion proteins.

The protein encoded by this gene interacts with atrophin-1. Atrophin-1 contains a polyglutamine repeat, expansion of which is responsible for dentatorubral and pallidoluysian atrophy. This encoded protein is characterized by two WW domains, a guanylate kinase-like domain, and multiple PDZ domains. It has structural similarity to the membrane-associated guanylate kinase homologue (MAGUK) family.

Function. Seems to act as a scaffold molecule at synaptic junctions by assembling neurotransmitter receptors and cell adhesion proteins. Plays a role in nerve growth factor (NGF)-induced recruitment of RAPGEF2 to late endosomes and neurite outgrowth. May play a role in regulating activin-mediated signaling in neuronal cells. Enhances the ability of PTEN to suppress AKT1 activation. Plays a role in receptor-mediated clathrin-dependent endocytosis which is required for ciliogenesis.

Subunit / interactions. Interacts (via its WW domains) with DRPLA. Interacts (via its second PDZ domain) with PTEN (via unphosphorylated C-terminus); this interaction diminishes the degradation rate of PTEN. Interacts (via guanylate kinase domain) with DLGAP1. Interacts (via the PDZ domains) with GRIN2A, GRID2 and NLGN1. Interacts with CTNND2, CTNNB1, MAGUIN-1, ACVR2A, SMAD2 and SMAD3. Part of a complex consisting of MAGI2/ARIP1, ACVR2A, ACVR1B and SMAD3. May interact with HTR2A. Interacts with IGSF9, RAPGEF2 and HTR4. Identified in a complex with ACTN4, CASK, IQGAP1, NPHS1, SPTAN1 and SPTBN1. Found in a complex, at least composed of KIDINS220, MAGI2, NTRK1 and RAPGEF2; the complex is mainly formed at late endosomes in a NGF-dependent manner. Interacts with RAPGEF2; the interaction occurs before or after nerve growth factor (NGF) stimulation. Interacts (via PDZ domain) with KIDINS220 (via C-terminal domain). Interacts with DDN. Interacts with DLL1. Found in a complex with IGSF9B and NLGN2; the interaction with IGSF9B is mediated via the PDZ 5 and PDZ 6 domains, while the interaction with NLGN2 is mediated via the WW1, WW2 and PDZ2 domains. Interacts (via PDZ 6 domain) with USH1G (via SAM domain); the interaction is triggered by phosphorylation of USH1G by CK2 and negatively regulates MAGI2-mediated endocytosis.

Disease relevance. Nephrotic syndrome 15 (NPHS15) [MIM:617609] A form of nephrotic syndrome, a renal disease clinically characterized by severe proteinuria, resulting in complications such as hypoalbuminemia, hyperlipidemia and edema. Kidney biopsies show non-specific histologic changes such as focal segmental glomerulosclerosis and diffuse mesangial proliferation. NPHS15 is an autosomal recessive form with onset in the first months of life. Disease severity is variable. Some patients show rapid progression to end-stage renal failure. The disease is caused by variants affecting the gene represented in this entry.

Similarity. Belongs to the MAGUK family.

Enriched among interaction partners

Reactome pathways and GO biological processes over-represented among this gene’s 123 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
