Abstract:
NAADP is one of the most potent calcium mobilizing second messengers. Only recently, two NAADP-binding proteins have been identified: HN1L/JPT2 and LSM12. Further, ASPDH was suggested as a less selective binding partner. Apart from this newly uncovered link, little is known about the shared mechanisms between these proteins. The aim of this review is to assess potential functional connections between NAADP and its binding proteins. We here give a description of two major links. For one, HN1L/JPT2 and LSM12 both have potent oncogenic functions in several cancer types. Second, they are involved in similar cellular pathways in both cancer and immunity.
Insights
Nicotinic acid adenine dinucleotide phosphate (NAADP) signaling involves newly identified HN1L/JPT2 and LSM12 proteins. These proteins share oncogenic functions and roles in cancer and immunity pathways, suggesting novel therapeutic targets.
Area of Science:
- Molecular Biology
- Cell Signaling
- Cancer Research
- Immunology
Background:
- Nicotinic acid adenine dinucleotide phosphate (NAADP) is a potent calcium-mobilizing second messenger.
- Two NAADP-binding proteins, HN1L/JPT2 and LSM12, were recently identified.
- ASPDH is also a potential, less selective NAADP-binding partner.
Conclusions:
- NAADP-binding proteins HN1L/JPT2 and LSM12 play critical roles in cancer development and progression.
- Shared involvement in cancer and immunity pathways suggests these proteins are key regulators.
- Understanding these connections may reveal novel therapeutic strategies for cancer and immune-related diseases.
