Abstract

Nicotinic acid adenine dinucleotide phosphate (NAADP) is a universal Ca2+ mobilizing second messenger essential for initiation of Ca2+ signaling. Recently, novel molecular mechanisms of both its rapid formation upon receptor stimulation and its mode of action were discovered. Dual NADPH oxidase 2 (DUOX2) and hematological and neurological expressed 1-like protein (HN1L)/Jupiter microtubule-associated homolog 2 (JPT2) were discovered as NAADP-forming enzyme and NAADP receptor/binding protein-the new kids on the block. These novel aspects are reviewed and integrated into the previous view of NAADP signaling.

Keywords: Ca2+ microdomains; Ca2+ signaling; NAADP; dual NADPH oxidase (DUOX); hematological and neurological expressed 1-like protein (HN1L)/Jupiter microtubule-associated homolog 2 (JPT2); ryanodine receptor (RYR); two-pore channel (TPC).
