CC -!- FUNCTION: Regulates the trafficking to the somatodendritic compartment
CC and gating properties of AMPA-selective glutamate receptors (AMPARs).
CC Promotes their targeting to the cell membrane and synapses and
CC modulates their gating properties by slowing their rates of activation,
CC deactivation and desensitization. Does not show subunit-specific AMPA
CC receptor regulation and regulates all AMPAR subunits. Thought to
CC stabilize the calcium channel in an inactivated (closed) state.
CC {ECO:0000250|UniProtKB:Q8VHX0}.
CC -!- SUBUNIT: The L-type calcium channel is composed of five subunits:
CC alpha-1, alpha-2/delta, beta and gamma. Acts as an auxiliary subunit
CC for AMPA-selective glutamate receptors (AMPARs). Found in a complex
CC with GRIA1, GRIA2, GRIA3, GRIA4, CNIH2, CNIH3, CACNG2, CACNG4, CACNG5,
CC CACNG7 and CACNG8. Interacts with AP4M1 and GRIA1; associates GRIA1
CC with the adaptor protein complex 4 (AP-4) to target GRIA1 to the
CC somatodendritic compartment of neurons. {ECO:0000250|UniProtKB:Q8VHX0,
CC ECO:0000250|UniProtKB:Q9JJV5}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255}; Multi-pass membrane
CC protein {ECO:0000255}. Note=Displays a somatodendritic localization and
CC is excluded from axons in neurons. {ECO:0000250|UniProtKB:Q9JJV5}.
CC -!- SIMILARITY: Belongs to the PMP-22/EMP/MP20 family. CACNG subfamily.
CC {ECO:0000305}.
