signaalisarja
Signaalisarja, also known as a signal sequence, is a specific pattern of amino acids found at the N-terminus (the amino end) of certain proteins. This sequence serves as a signal for the protein to be transported to its correct location within the cell or to be secreted outside the cell. The most well-known signal sequence is the N-terminal signal peptide, which is typically 15-30 amino acids long and is recognized by the signal recognition particle (SRP) in the endoplasmic reticulum (ER) during protein synthesis.
The signal sequence can be classified into several types based on its function. For example, the classical
The signal sequence is usually removed from the mature protein after it has been transported to its
Signaalisarja plays a crucial role in protein trafficking and localization within the cell, ensuring that proteins
