CC -!- FUNCTION: Acts in different tissues through interaction to nicotinic
CC acetylcholine receptors (nAChRs). The proposed role as modulator of
CC nAChR activity seems to be dependent on the nAChR subtype and
CC stoichiometry, and to involve an effect on nAChR trafficking and its
CC cell surface expression, and on single channel properties of the nAChR
CC inserted in the plasma membrane.Modulates functional properties of
CC nicotinic acetylcholine receptors (nAChRs) to prevent excessive
CC excitation, and hence neurodegeneration. Enhances desensitization by
CC increasing both the rate and extent of desensitization of alpha-4:beta-
CC 2-containing nAChRs and slowing recovery from desensitization. Promotes
CC large amplitude ACh-evoked currents through alpha-4:beta-2 nAChRs. Is
CC involved in regulation of the nAChR pentameric assembly in the
CC endoplasmic reticulum. Shifts stoichiometry from high sensitivity
CC alpha-4(2):beta-2(3) to low sensitivity alpha-4(3):beta-2(2) nAChR. In
CC vitro modulates alpha-3:beta-4-containing nAChRs. Reduces cell surface
CC expression of (alpha-3:beta-4)(2):beta-4 and (alpha-3:beta-4)(2):alpha-
CC 5 nAChRs suggesting an interaction with nAChR alpha-3(-):(+)beta-4
CC subunit interfaces and an allosteric mode. Corresponding single channel
CC effects characterized by decreased unitary conductance, altered burst
CC proportions and enhanced desensitization/inactivation seem to depend on
CC nAChR alpha:alpha subunit interfaces and are greater in (alpha-3:beta-
CC 2)(2):alpha-3 when compared to (alpha-3:beta-2)(2):alpha-5 nAChRs.
CC Prevents plasticity in the primary visual cortex late in life.
CC {ECO:0000250|UniProtKB:P0DP58, ECO:0000250|UniProtKB:P0DP60}.
CC -!- SUBUNIT: Interacts with nAChRs containing alpha-4:beta-2
CC (CHRNA4:CHRNB2) and alpha-7 (CHRNA7) subunits. Interacts with CHRNA4
CC probably in the endoplasmic reticulum prior to nAChR pentameric
CC assembly. {ECO:0000250|UniProtKB:P0DP60}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255}; Lipid-anchor, GPI-
CC anchor {ECO:0000255}. Cell projection, dendrite
CC {ECO:0000250|UniProtKB:P0DP60}. Endoplasmic reticulum
CC {ECO:0000250|UniProtKB:P0DP60}. Note=Detected in Purkinje cells soma
CC and proximal dendrites. {ECO:0000250|UniProtKB:Q9WVC2}.
