Anti-CD38 and Anti-CD3e Bispecific Antibody (scFv), BiTE, Recombinant

Description

CD38, also known as ADP­ribosyl cyclase, is a single-pass type II transmembrane protein. CD38 is expressed in B and T lymphocytes, osteoclasts, and in cardiac, pancreatic, liver and kidney cells. CD38 is a multifunctional ectoenzyme that catalyzes the synthesis and hydrolysis of cyclic ADP-ribose from NAD+ to ADP-ribose. Through its production of cyclic ADP­ribose, CD38 modulates calcium signaling in many types of cells, including neutrophils and pancreatic β cells. CD38 also functions in cell adhesion signal transduction. CD38 has been used as a prognostic marker in leukemia and a surface marker to identify plasma cells. CD38 also plays a key role in neuropeptide release.  It may regulate maternal and social behaviors, thereby contributing to neurodevelopmental disorders. Defects of CD38 are associated with impaired immune responses, metabolic disturbances, and behavioral modifications.  CD38 is implicated in human immunodeficiency virus (HIV) infection, leukemias, myelomas, solid tumors, type II diabetes mellitus, and bone metabolism. In addition to immune responses, CD38 may play an equally important role as an intrinsic pulmonary component. CD38 is the main cellular NADase in mammalian tissues to control cellular NAD levels, making CD38 a promising therapeutic target for multiple pathological conditions.
