SERPINA9

Serpin A9 also known as centerin or GCET1 is a is_associated_with::protein that in humans is encoded by the SERPINA9 is_associated_with::gene located on is_associated_with::chromosome 14q32.1. Serpin A9 is a member of the is_associated_with::serpin family of serine protease inhibitors.

Function
The expression of SERPINA9 is restricted to is_associated_with::germinal center is_associated_with::B cells and lymphoid malignancies. SERPINA9 is likely to function in vivo in the germinal center as an efficient inhibitor of trypsin-like proteases.
