FITC-Labeled CD38 Protein, Human (HEK293, His)

The CD38 protein plays a key role in cell signaling, proficiently synthesizing cyclic ADP-ribose (cADPR) as a critical second messenger for glucose-induced insulin secretion. It also promotes the synthesis of the calcium mobilizer niacin-adenine dinucleotide phosphate (NAADP+). FITC-Labeled CD38 Protein, Human (HEK293, His) is the recombinant human-derived FITC-Labeled CD38 protein, expressed by HEK293 , with C-His labeled tag. The total length of FITC-Labeled CD38 Protein, Human (HEK293, His) is 258 a.a., with molecular weight of 40-50 kDa.

The CD38 Protein assumes a pivotal role in cellular signaling, being a proficient synthesizer of cyclic ADP-ribose (cADPR), a recognized second messenger crucial for glucose-induced insulin secretion. Moreover, it facilitates the synthesis of the calcium mobilizer nicotinate-adenine dinucleotide phosphate, NAADP(+), derived from 2'-phospho-cADPR and nicotinic acid, as well as from NADP(+) and nicotinic acid. Operating at both pH 5.0 and pH 7.4, CD38 Protein exhibits a preference for transforming 2'-phospho-cADPR into NAADP(+) while selectively cleaving NADP(+) to cADPR and ADPRP rather than generating NADDP(+). Notably, it also showcases cADPR hydrolase activity, highlighting its multifaceted role in the dynamic regulation of these crucial signaling molecules. The integration of these activities underscores the significance of CD38 Protein in modulating cellular responses, particularly in the context of insulin secretion and calcium mobilization.
