Introduction A cellular response produced as a result of a series of molecular processes, most frequently protein phosphorylation catalyzed by protein kinases, known as signal transduction, which is the process by which a chemical or physical signal is transferred through a cell. Although in some instances the term sensor is used, generally speaking, proteins that detect stimuli are referred to as receptors. Definition The process through which a cell reacts to things outside of it via signaling molecule that is both inside and on its surface. The majority of molecules that result in signal transduction are chemical substances ... Read More

Introduction A signal peptide, also known as a signal sequence, is a brief peptide that is typically 16 to 30 amino acids long. It can also occasionally be found nonclassically at the C or internal regions of most newly synthesised proteins that are headed for the secretory pathway. These proteins include those that are either inserted into most cellular membranes or found inside specific organelles, such as the endoplasmic reticulum, Golgi, or endosomes. The majority of type II and multi-spanning membrane-bound proteins are directed to the secretory pathway by their first transmembrane domain, which biochemically resembles a signal sequence ...
