CC -!- FUNCTION: Probable adapter protein that bind to and organize the
CC subcellular localization of a variety of membrane proteins containing
CC some PDZ recognition sequence. Involved in the clustering of various
CC receptors, possibly by acting at the receptor internalization level.
CC Plays a role in synaptic plasticity by regulating the trafficking and
CC internalization of AMPA receptors. May be regulated upon PRKCA
CC activation. May regulate ASIC1/ASIC3 channel. Regulates actin
CC polymerization by inhibiting the actin-nucleating activity of the
CC Arp2/3 complex; the function is competitive with nucleation promoting
CC factors and is linked to neuronal morphology regulation and AMPA
CC receptor (AMPAR) endocytosis. Via interaction with the Arp2/3 complex
CC involved in regulation of synaptic plasicity of excitatory synapses and
CC required for spine shrinkage during long-term depression (LTD).
CC Involved in regulation of astrocyte morphology, antagonistic to Arp2/3
CC complex activator WASL/N-WASP function (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Monomer and homodimer. Interacts with CXADR. Interacts
CC presynaptically with the glutamate receptors GRIA2, GRIA3, GRIK3,
CC isoform 3 of GRIA4, isoform A of GRM4, GRM7 and GRM8; with NAPA and
CC NAPB; and with BTG2. The interaction with NAPA and NAPB disrupts the
CC interaction with GRIA2, conducting to the internalization of GRIA2.
CC Interacts with PRKCA; with the amine transporters SLC6A2 and SLC6A3;
CC with the channels ASIC1 and ASIC2; with the GTP-binding proteins ARF1
CC and ARF3; with the ephrin receptor tyrosine kinases EPHA7, EPHB1 and
CC EPHB2; with ERBB2 and through its PDZ domain with the C-terminal tail
CC of PRLHR. Interacts with UNC5A. Interacts (via AH domain) with
CC NCS1/FREQ; in a calcium-dependent manner. Interacts with F-actin and
CC associates with the ARP2/3 complex. Interacts (via PDZ domain) with
CC ARF1 (activated); the interaction blocks Arp2/3 complex inhibition (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, perinuclear region {ECO:0000250}.
CC Membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}.
CC Membrane {ECO:0000250}; Lipid-anchor {ECO:0000250}. Postsynaptic
CC density {ECO:0000250}. Synapse, synaptosome {ECO:0000250}. Cytoplasm,
CC cytoskeleton {ECO:0000250}. Note=Also membrane-associated, present at
CC excitatory synapses. {ECO:0000250}.
CC -!- DOMAIN: The AH domain mediates binding to F-actin. {ECO:0000250}.
CC -!- DOMAIN: The unoccupied PDZ domain is probably involved in allosteric
CC modulation by forming an intramolecular bridge with the AH domain
CC leading to a 'closed' formation. Binding of a PDZ ligand, such as
CC GRIA2, allows enhanced interactions with F-actin and the Arp2/3 complex
CC thus enhanced inhibition of actin polymerization (By similarity).
CC {ECO:0000250}.
CC -!- PTM: Phosphorylation at Thr-82 appears to inhibit the interaction with
CC AMPA receptors. {ECO:0000250}.
CC -!- PTM: Palmitoylation on Cys-415 is essential for long-term synaptic
CC depression (LTD). {ECO:0000250}.
