Endoplasmic reticulum resident protein(Redirected from ER retention)
Their localization to the ER often depends on certain sequences of amino acids located at the N-terminus or C-terminus. The classical ER retention signal is the C-terminal KDEL sequence for lumen bound proteins and KKXX for transmembrane localization. These signals allow for retrieval from the Golgi apparatus by ER retention receptors, effectively maintaining the protein in the ER. Other mechanisms for ER retention are being studied but are not as well characterized as signal retention.
