CALHM1 Activators

CALHM1 Activators represent a diverse set of chemicals known to influence the activity or expression of the Calcium Homeostasis Modulator 1 (CALHM1) protein. These compounds can modulate the function of CALHM1 through various mechanisms, highlighting the multifaceted regulation of this ion channel protein. Some compounds directly interact with CALHM1, affecting its ion-conducting properties, while others exert their effects indirectly through associated cellular pathways.

Among the activators, ATP and adenosine play roles in modulating CALHM1-mediated ion currents. These nucleotides interact with numerous cellular receptors, leading to a cascade of intracellular events that can culminate in the modulation of CALHM1. Similarly, forskolin, by elevating intracellular cAMP levels, can have an influence on CALHM1 activity. Calcium modulators such as ionomycin, BAPTA, and EGTA, by altering intracellular calcium dynamics, play a pivotal role in CALHM1's activity, given that CALHM1 is responsive to calcium concentrations. Compounds like 2-APB and capsaicin are known to affect various ion channels, suggesting a potential modulation of CALHM1 function. On the other hand, compounds like ruthenium red, which might often act as inhibitors for some channels, can have a nuanced effect on CALHM1, depending on the context. Additionally, compounds like caffeine, thapsigargin, and ryanodine, which modulate intracellular calcium stores, can also influence CALHM1-mediated calcium dynamics.
