靶點(diǎn)詳情

  • 功能：
    Intracellular channel initially characterized as a non-selective Ca(2+)-permeable channel activated by NAADP (nicotinic acid adenine dinucleotide phosphate), it is also a highly-selective Na(+) channel activated directly by PI(3,5)P2 (phosphatidylinositol 3,5-bisphosphate). Localizes to the lysosomal and late endosome membranes where it regulates organellar membrane excitability, membrane trafficking, and pH homeostasis. Is associated with a plethora of physiological processes, including mTOR-dependent nutrient sensing, skin pigmentation and autophagy. Ion selectivity is not fixed but rather agonist-dependent and under defined ionic conditions, can be readily activated by both NAADP and PI(3,5)P2. As calcium channel, it increases the pH in the lysosomal lumen, as sodium channel, it promotes lysosomal exocytosis. Plays a crucial role in endolysosomal trafficking in the endolysosomal degradation pathway and is potentially involved in the homeostatic control of many macromolecules and cell metabolites. Unlike the voltage-dependent TPCN1, TPCN2 is voltage independent and can be activated solely by PI(3,5)P2 binding. In contrast, PI(4,5)P2, PI(3,4)P2, PI(3)P and PI(5)P have no obvious effect on channel activation.; (Microbial infection) During Ebola virus (EBOV) infection, controls the movement of endosomes containing virus particles and is required by EBOV to escape from the endosomal network into the cell cytoplasm.

    1. Under normal Mg(2+) conditions, TPC2 promotes osteoclastogenesis. Under low-Mg(2+) conditions, TPC2 inhibited, rather than promoted, the osteoclast differentiation, and the phosphatidylinositol 3,5-bisphosphate (PI(3,5)P2) signaling pathway played a role in the TPC2 activation under low-Mg(2+) conditions. PMID: 29084844
    2. Data (including data from studies using tissue from knockout mice) suggest that beta-adrenergic stimulation of pancreas leads to glucagon secretion by hierarchy of calcium signaling in glucagon-secreting cell; such signaling is initiated by cAMP-induced Tpc2-dependent calcium release from acidic stores and is further amplified by calcium release from endoplasmic reticulum. PMID: 29563152
    3. Study identifies two-pore channel 2 (TPC2) as the first reported melanosomal cation conductance by directly patch-clamping skin and eye melanosomes. TPC2 is shown to function as a negative regulator of pigmentation by increasing melanosome membrane potential and melanosome acidity. PMID: 27231233
    4. High TPC2 expression is associated with lung metastasis in breast cancer. PMID: 28108508
    5. Electron micrographs of hearts from TPC1/TPC2 double knockout mice showed that cardiomyocytes contained large numbers of immature lysosomes compared to wild-type mice. PMID: 26757341
    6. observations define a role for NAADP and TPC2 at lysosomal/sarcoplasmic reticulum junctions as unexpected but major contributors in the acute actions of beta-adrenergic signaling in the heart PMID: 26438825
    7. TPC2 plays a crucial role in trafficking in the endolysosomal degradation pathway and in fatty liver disease. PMID: 25144390
    8. Genetic ablation of endolysosomal TPC1 or TPC2 channels attenuates glucose- and sulfonylurea-induced membrane currents, depolarization, cytoplasmic Ca2+ signals, and insulin secretion in pancreatic beta cells. PMID: 26152717
    9. Tpcn2 knockout mice demonstrated a significant decrease in fasting glucose levels and insulin response to a glucose challenge. PMID: 25236446
    10. Mice lacking TPC2 display muscle atrophy and altered autophagy. PMID: 25480788
    11. It was concluded that Tpcn1/2(-/-) mice show mature-onset obesity due to reduced lipid availability and use, and a defect in beta-adrenergic receptor signaling, leading to impaired thermogenic activity, in brown adipose tissue. PMID: 25545384
    12. These results demonstrate that a VEGFR2/NAADP/TPC2/Ca(2+) signaling pathway is critical for VEGF-induced angiogenesis PMID: 25331892
    13. Findings indicate that TPC2 have important but distinct roles from TPC1 in the endo-lysosomal pathway. PMID: 25135478
    14. TPC2 signaling inhibits embryonic stem cell entry to early neural progenitors, but is required for late neuronal differentiation. PMID: 23776607
    15. We find alterations in two-pore calcium channel protein expression, with loss of presenilin preventing the formation of a high molecular weight species of TPC1 and TPC2. PMID: 23103503
    16. Study identifies an endolysosomal ATP-sensitive Na channel - a complex formed by two-pore channels TPC1 and TPC2; channel complex detects nutrient status, becomes constitutively open upon nutrient removal and mTOR translocation off the lysosomal membrane, and controls the lysosome's membrane potential, pH stability, and amino acid homeostasis. PMID: 23394946
    17. TPC2 is a novel critical molecule for osteoclastogenesis. PMID: 22833668
    18. Study finds by direct patch-clamp analysis of endolysosomal membranes that PI(3,5)P2 specifically activates TPCs and, unexpectedly, that nicotinic acid adenine dinucleotide phosphate does not. TPC1 and TPC2-mediated currents are selective for Na+, which is the predominant cation in the lysosome. PMID: 23063126
