Knox RTN in PD final accepted revision with figures
... The degree of membrane constriction produced by RTNs is dependent on their concentration (Hu et al., 2008). Our experiments provide no information on whether or not RTNLBs are enriched within PD. However, the ability of RTNLBs to constrict ER tubules depends on their oligomerisation, which in turn c ...

Signal transduction
Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell. In turn, this receptor triggers a biochemical chain of events inside the cell, creating a response. Depending on the cell, the response alters the cell's metabolism, shape, gene expression, or ability to divide. The signal can be amplified at any step. Thus, one signaling molecule can cause many responses.
