SK channel
SK Channel
SK Channel (pronounced as "ess-kay channel"), also known as Small Conductance Calcium-Activated Potassium Channel, is a type of potassium channel that is activated by calcium ions.
Pronunciation
SK Channel is pronounced as "ess-kay channel".
Etymology
The term "SK Channel" is derived from the words "Small Conductance" and "Potassium Channel". The "SK" in SK Channel stands for "Small Conductance", indicating the small conductance of these channels to potassium ions. The term "Channel" refers to the pathway through which ions move across the cell membrane.
Function
SK Channels play a crucial role in the regulation of neuronal excitability and the modulation of synaptic transmission. They are also involved in the regulation of heart rate and smooth muscle tone.
