Secondary Information

Protein Function human CD38 -transmembrane glycoprotein involved in lymphocyte activation and adhesion to endothelium; implicated in activities typical of cell surface receptors, such as signaling for activation and proliferation events and heterotypic cell adhesion; involved in the regulation of intracellular calcium levels in several cell systems
Biochemical Properties ectocellular domain of the molecule possesses properties of a bifunctional enzyme catalyzing both the synthesis from NAD+ and the hydrolysis of the calcium-releasing metabolite cyclic ADP-ribose;
PTMs Glycosylated: potential N-linked glycosylation sites asparagine residues, N100, N164, N209 and N219
Site(s) of PTM(s)

SCOP Class : Alpha and beta proteins (a/b)
Fold : Rossmann(2x3)oid (Flavodoxin-like)
Superfamily : N-(deoxy)ribosyltransferase-like
Family : ADP ribosyl cyclase-like
Domain Name : 3KOU B:39-276

CATH Matched CATH superfamily
Significance of PTMs ADP-ribosyl cyclase activity of CD38 showed a decrease in the Vmax following its treatment with N-glycosidase F , the extracellular non-glycosylated form of CD38 was still fully active and exhibited both cyclase and hydrolase activities; Glycosylation prevents CD38 protein from forming inter-molecular cross-links
