Some of them remain in the ER, where they function as part of the organelle.
These complexes usually dissociate more rapidly at mildly acidic pH, where they are formed intracellularly, as compared to neutral pH, where they function at the cell surface.
Histidine kinases are found in most bacteria, archaea, and lower eukaryotic species such as slime molds, fungi, and plants where they function in two-component signal transduction pathways.
The fibrillar collagens, types I, II, and III, are the most abundant natural polymers in the body and are found throughout the interstitial spaces where they function to impart overall structural integrity and strength to tissues.
All characterized mammalian aquaporins (AQPs) are localized to plasma membranes where they function chiefly to mediate water transport across cells.
Network courses appeared in the eighties in a specific university context, where they function as classroom or as campus.
The phones are then placed throughout a forest, generally high in trees to avoid detection, where they function as listening devices.
Type III forms are found only in archaea where they function as Rubisco in AMP metabolism.
In vertebrates, FGF3 and FGF8 are expressed in pharyngeal endoderm where they function to induce cartilage.
Messenger RNA localization is a mechanism which allows eukaryotic cells to synthesize proteins close to where they function.
The apoptotic caspases can be categorized as initiators (apical caspases) or effectors (executioner caspases) of apoptosis, depending on where they function in the apoptotic cascade [10].
