kationcsatornák
Kationcsatornák, often translated as cation channels, are a class of transmembrane proteins that form pores through cell membranes, allowing the passage of positively charged ions, primarily sodium (Na+), potassium (K+), calcium (Ca2+), and magnesium (Mg2+), across the membrane. These channels play a crucial role in a multitude of physiological processes, including nerve impulse transmission, muscle contraction, hormone secretion, and cellular homeostasis.
The selective permeability of cation channels to specific ions is determined by the arrangement of amino acids
Dysfunction of cation channels is implicated in a wide range of diseases, including epilepsy, cardiac arrhythmias,
