WebOnly a few reports describe potential mechanisms of cytoplasmic retention of p21. In general, the nuclear localization signal (NLS) and the nuclear export signal (NES) motifs are responsible for the active shuttling of proteins between the nucleus and the cytoplasm. ER retention refers to proteins that are retained in the endoplasmic reticulum, or ER, after folding; these are known as ER resident proteins. Protein localization to the ER often depends on certain sequences of amino acids located at the N terminus or C terminus. These sequences are known as signal peptides, molecular signatures, or sorting signals.
