Human Serum Amyloid P is a small, non-fibrillar glycoprotein found in normal serum and in all amyloid deposits. SAP has a pentagonal structure and modulates immunologic responses in man, inhibits elastase and has been suggested as an indicator of liver disease and has 51% sequence homology with C-reactive protein (CRP).

NCBI Summary for SAP
The protein encoded by this gene is a glycoprotein, belonging to the pentraxin family of proteins, which has a characteristic pentameric organization. These family members have considerable sequence homology which is thought to be the result of gene duplication. The binding of the encoded protein to proteins in the pathological amyloid cross-beta fold suggests its possible role as a chaperone. This protein is also thought to control the degradation of chromatin. It has been demonstrated that this protein binds to apoptotic cells at an early stage, which raises the possibility that it is involved in dealing with apoptotic cells in vivo.

UniProt Comments for SAP
APCS: Can interact with DNA and histones and may scavenge nuclear material released from damaged circulating cells. May also function as a calcium-dependent lectin. SAP is a precursor of amyloid component P which is found in basement membrane and associated with amyloid deposits. Belongs to the pentaxin family.
