Protein-coding gene in the species Homo sapiens
Serpin A9 also known as centerin or GCET1 is a protein that in humans is encoded by the SERPINA9 gene located on chromosome 14q 32.1.[ 5] serpin family of ser ine p rotease in hibitors.
The expression of SERPINA9 is restricted to germinal center B cells and lymphoid malignancies . SERPINA9 is likely to function in vivo in the germinal center as an efficient inhibitor of trypsin-like proteases.[ 6] [ 7] [ 8]
