IP3 molecules diffuse through the cytoplasm and bind to the endoplasmic reticulum (ER) resulting in the opening of calcium channels [31?4]. The released calcium from the ER into the cytoplasm is free to bind important regulatory proteins including but not restricted to calmodulin and calcineurin. The binding of calcium to calmodulin mediates critical o Mon, 15 May 2023 15:06:14 UTC en
