... Sometimes a single polypeptide is sufficient for the protein to be active; we then talk of a protein that acts as a monomer. Often, however, two or more polypeptides need to interact to allow a protein to perform its particular function. If this is the case, we talk of a dimer; and so on through tri ...

Improved topology prediction using the terminal
... The positive-inside rule is used to allow for less hydrophobic TMsegments to be recognized if this results in that more positive residues are found in periplasmic loops. Exactly how the balance between the hydrophobicity cut-off and the positive-inside rule is optimized varies between methods. In so ...

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.
