Background
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. [provided by RefSeq, Jul 2008],
Function
function:Seems to act as scaffold molecule at synaptic junctions by assembling neurotransmitter receptors and cell adhesion proteins. May play a role in regulating activin-mediated signaling in neuronal cells. Enhances the ability of PTEN to suppress AKT1 activation.,similarity:Belongs to the MAGUK family.,similarity:Contains 1 guanylate kinase-like domain.,similarity:Contains 2 WW domains.,similarity:Contains 6 PDZ (DHR) domains.,subcellular location:Membrane-associated in synaptosomes.,subunit:Interacts via its WW domains with DRPLA. Interacts via its second PDZ domain with PTEN unphosphorylated C-terminus; this interaction diminishes the degradation rate of PTEN (By similarity). Interacts through its guanylate kinase domain with DLGAP1 (By similarity). Interacts through the PDZ domains with GRIN2A, GRID2 and NLGN1 (By similarity). Interacts with CTNND2, CTNNB1, MAGUIN-1, ACVR2A, SMAD2
