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.
