Cyclic ADP Ribose Hydrolase (CD38) Antibody

Background

CD38 is a multifunctional membrane glycoprotein expressed on a variety of cells, including immune cells (B cells, T cells, monocytes, and natural killer cells), as well as non-hematopoietic cells like those in the pancreas, brain, and muscle. Initially identified as a cell-surface receptor on lymphocytes, CD38 has since been recognized for its roles in enzyme-mediated metabolism, cell adhesion, and signal transduction. This protein is particularly well-known for its enzymatic activity in catalyzing the synthesis and hydrolysis of cyclic ADP-ribose (cADPR) from NAD+, which serves as an important second messenger in calcium signaling pathways. CD38 plays crucial roles in the regulation of intracellular calcium levels, influencing processes such as cell activation, proliferation, and differentiation.
