8.A.82.1.1
Calmodulin regulates various channels, including several voltage-gated calcium channels (VGCCs), transient receptor potential channels (TRPCs), NMDA receptors, calcium channels dependent on cyclic nucleotides, and those located in the endoplasmic reticulum such as ryanodine receptors and all isoforms of IP3-dependent receptors (Rebas et al. 2012).  It also mediates secretion in animals of small intron-less proteins (Shao and Hegde, 2011).
