FLASH GENE DNA RNA EXPRESSION PROTEIN DISORDER ANIMAL & CELL MODELS

PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	a large N terminal extracellular domain, and AAs in the extracellular domain show relatively weak changes in interactions with the local environment during channel gating
	four transmembrane (4TM) segments with the M2 domain comprising the cation-selective pore

HOMOLOGY

interspecies

ortholog to murine Chrnb1

Homologene

FAMILY

cholinergic receptor family

CATEGORY

receptor membrane

SUBCELLULAR LOCALIZATION	plasma membrane,junction
	intracellular

basic FUNCTION	cholinergic receptor, nicotinic
	ligand gated ion channel activity
	involved in muscle contraction and in synaptic transmission
	after binding acetylcholine, involved in opening of an ion-conducting channel across the plasma membrane (through an extensive change in conformation that affects all
	subunits )
	is passive in the transfer of the energy of binding from the extracellular domain (ECD) to the channel gate
