Relays at the membrane

摘要

The Wnt signalling pathway is a major route by which the cell conveys information from its exterior to the nucleus. A gap in the sequence of signalling proteins has now been filled. The process of signal transduction allows a cell to receive messages from its environment and transfer this signal from the membrane through the cytoplasm and into the nucleus. Here the signal alters the expression of the various genes that contribute to the cells response. Regardless of the signal's nature, the general logic of the transduction pathways that are triggered by protein ligands is roughly the same.
