Tyrosine kinases are signaling molecules that are common to all metazoans and are involved in the regulation of many cellular processes such as proliferation and survival. While most attention has been devoted to tyrosine kinases signaling at the plasma membrane and the cytosol, very little attention has been dedicated to signaling at endomembranes. In this review, I will discuss recent evidence that we obtained on signaling of tyrosine kinases at the surface of the endoplasmic reticulum (ER), as well as in the lumen of this organelle. I will discuss how tyrosine kinase signaling might regulate ER proteostasis and the implication thereof to general cell physiology.
