Background: SAA4 is a member of the SAA family.SAA proteins are family of apolipoproteins of high density lipoprotein (HDL). They can be separated into two distinct groups. First group (SAA1; SAA2; and SAA3) consists of acute phase reactant whose expression level increase in the blood in a response to trauma; infection; inflammation; and neoplasia. These acute phase SAAs associates with HDL during inflammation and remodel the HDL particle by displacing Apo-A1. The second distinct group consists of SAA4 and SAA5 which exist as the minor apolipoproteins on HDL; but this group of SAA constitutes more than 90% of all the SAA during homeostasis; and it is thought to play a role in the normal functioning of the HDL particle. SAA4 is a constitutively expressed protein which expressed only in humans and mice.It is connected almost completely with lipoproteins of the high density range. The physiological function of SAA4 is unknown; and its serum concentration has no association with those of other major apolipoproteins.
