P-type Calcium Channels

P-type calcium channels are specialized proteins found in cell membranes that allow calcium ions to enter cells. They play a crucial role in various functions, including muscle contraction, hormone release, and neurotransmitter signaling in the nervous system. When these channels open, calcium flows into the cell, triggering important biological processes. P-type channels are named for their unique properties and are particularly abundant in certain brain areas and heart tissues. Dysfunction in these channels can be linked to various health issues, highlighting their importance in normal cellular function.
