Entrez Gene

Human Gene ID: 952

Description: The protein encoded by this gene is a non-lineage-restricted, type II transmembrane glycoprotein that synthesizes and hydrolyzes cyclic adenosine 5'-diphosphate-ribose, an intracellular calcium ion mobilizing messenger. The release of soluble protein and the ability of membrane-bound protein to become internalized indicate both extracellular and intracellular functions for the protein. This protein has an N-terminal cytoplasmic tail, a single membrane-spanning domain, and a C-terminal extracellular region with four N-glycosylation sites. Crystal structure analysis demonstrates that the functional molecule is a dimer, with the central portion containing the catalytic site. It is used as a prognostic marker for patients with chronic lymphocytic leukemia. Alternative splicing results in multiple transcript variants.

Mouse Gene ID: 12494

Description: This gene encodes a non-lineage-restricted, type II transmembrane glycoprotein that synthesizes and hydrolyzes cyclic adenosine 5'-diphosphate-ribose, an intracellular calcium ion mobilizing messenger. The release of soluble protein and the ability of membrane-bound protein to become internalized indicate both extracellular and intracellular functions for the protein. This protein has an N-terminal cytoplasmic tail, a single membrane-spanning domain, and a C-terminal extracellular region with four N-glycosylation sites. Knockout mice deficient for this gene display altered humoral immune responses. In addition, knockout mice exhibit higher locomotor activity and defects in nurturing and social behaviors.

UniProt

Human UniProt ID: P28907

Function: Synthesizes cyclic ADP-ribose (cADPR), a second messenger for glucose-induced insulin secretion. Synthesizes the Ca2+ mobilizer nicotinate-adenine dinucleotide phosphate, NAADP+, from 2'-phospho-cADPR and nicotinic acid, as well as from NADP+ and nicotinic acid. At both pH 5.0 and pH 7.4 preferentially transforms 2'-phospho-cADPR into NAADP+, while preferentially cleaving NADP+ to cADPR and ADPRP rather than into NADDP+ . Has cADPR hydrolase activity .

Molecular Function: Hydrolase, Receptor, Transferase

Mouse UniProt ID: P56528

Function: Synthesizes the second messengers cyclic ADP-ribose (cADPR) and nicotinate-adenine dinucleotide phosphate (NAADP), the former a second messenger for glucose-induced insulin secretion, the latter a Ca2+ mobilizer. Also has cADPR hydrolase activity
