The HIN-200 family: More than interferon-inducible genes?

In addition to a role in interferon biology, there is now good evidence supporting a role for these proteins as regulators of cell proliferation and differentiation. The activity of HIN-200 proteins is not restricted to the hemopoietic system as they are expressed and can function in a variety of other cells and tissues. The importance of HIN-200 proteins in disease now is beginning to be understood as they appear to be involved in autoimmunity and may act as tumor suppressor proteins.
