Rab10 deficiency unexpectedly inhibits neuropeptide secretion through two distinct effects on the endoplasmic reticulum (ER), disrupting ER-regulated intracellular Ca²⁺ dynamics and impairing protein synthesis.
By influencing calcium homeostasis, local protein synthesis and the endoplasmic reticulum, a small protein called Rab10 emerges as a crucial cytoplasmic regulator of neuropeptide secretion.
