Question
Match each protein with its anatomical location and/or description Voltage-gated Na+ channels Choose... major component of the thin filament to which myosin binds blocks the actin-binding sites on the thin filament unless Ca2+ levels are high ion channel found in SR membrane through which Ca2+ leaves the SR generate and propagate action potentials in muscle cell membrane binds calcium and interacts with tropomyosin Troponin Acetylcholine receptor (AChR) motor protein with ATP-binding domain and actin-binding domain voltage-sensing protein embedded in the T-tubule membrane, interacts with RyR Actin Choose... Tropomyosin DHPR Choose... Myosin Choose...Explanation / Answer
Voltage gated Na+ channel: generate and propogate the action potential in muscle cell membrane
SERCA (SR Ca 2+ ATPase): ion channel found in SR membrane through which Ca2+ leaves the SR
Troponin: binds calcium and interact with tropomyosin
Acetylcholine receptor AChR: neurotransmitter receptor that initiates depolarization of muscle cell membrane
Ryanodine Receptor: transport calcium into the SR at the expenses of ATP hydrolysis
Actin : major component of the thin filament to which myosin binds
Tropomyosin: blocks the actin binding sites on the thin filament unless Ca2+ levels are high
DHPR: voltage sensing protein embedded in the T-tubule membrane interacts with RyR
Myosin: motor protein with ATP binding domain and actin binding domain
