NCIt definition : Acylation stimulating protein (76 aa, 9 kDa) is encoded by the human C3 gene. This
protein is involved in stimulating glucose uptake, triglyceride synthesis and nonesterified
fatty acid storage in adipocytes.;
NCIt note : Acylation stimulating protein (ASP) is comprised of amino acids 672-747 of complement
C3 and is produced through proteolysis of complement C3 into a C-terminal alpha chain
and a N-terminal beta chain (C3b) followed by further modification of the alpha chain
C-terminus yielding C3a anaphylatoxin. Then C3a anaphylatoxin is rapidly cleaved by
either carboxypeptidase B or N, which remove the C-terminal arginine residue, to generate
acylation stimulating protein.;
