NES

This nuclear export signal(NES)directs the protein out of the nucleus.

Usage and Biology

Regulating the output of many proteins from the nucleus depends on the presence of a nuclear export signal(NES) consisting of leucine-rich amino acids.(Fornerod et al., 1997);(Fischer et al., 1995). The shuttle receptor that appears to bind to the NES sequence and function in the protein output from the nucleus to the cytoplasm is CRM1 (chromosomal region maintenance)/export protein 1.(Richards et al., 1997) CRM1 binds to Ran GTPase and interacts with the nucleoporous components to translocate NES-containing proteins to the cytoplasm.(Stade et al., 1997)
