Three P-type Ca2+-transporting ATPases have been recognized in animal cells. Other cell types, such as yeast and plant, contain additional P-type Ca2+ pumps. This succinct chapter will concentrate on the animal pumps privileging recent developments, rather than established aspects that are adequately covered in a number of comprehensive reviews which ...
