About
====================

Landing page for the L-type calcium pump **CaL**.

CaL allows for calcium entry into the cell and is responsible for triggering muscle contraction predominantly within cardiac, skeletal and smooth muscle cells. 

When the cell membrane is depolarised above a given potential (such as during an action potential) the gated, voltage-dependent channel opens to allow for calcium entry.

CaLs are multisubunit complexes, consisting of a combination of alpha, beta, gamma and delta subunits. The channel activity is generally directed by the pore-forming and voltage-sensitive alpha subunit.

Other names: **Cav1**, **LCC**
