High affinity calcium-ion binding proteins (110 aa), part of a superfamily that includes calmodulin and troponin C. Parvalbumin is expressed at high levels in fast skeletal muscle and at low level in brain and some endocrine tissues. Parvalbumi n-β (oncomodulin) is found in early embryonic cells, in the placenta, in outer cochlear hair cells in the organ of Corti, and in tumours. Oncomodulin can act as a growth factor for neurons of the mature central and peripheral nervous systems.
