PMCA2

PMCA2 (Plasma Membrane Calcium ATPase 2) is a protein found in cell membranes that helps regulate calcium levels inside cells. Calcium is vital for various cellular functions, including nerve signaling and muscle activity. PMCA2 actively pumps excess calcium out of cells using energy from ATP, maintaining the proper balance needed for healthy cell function. It is especially important in the brain, where it supports nerve communication and plasticity. Proper operation of PMCA2 is crucial for normal neurological function and avoiding calcium-related cellular damage.
