Genes affected

EIF4ENIF1 (HGNC:16687): (eukaryotic translation initiation factor 4E nuclear import factor 1) The protein encoded by this gene is a nucleocytoplasmic shuttle protein for the translation initiation factor eIF4E. This shuttle protein interacts with the importin alpha-beta complex to mediate nuclear import of eIF4E. It is predominantly cytoplasmic; its own nuclear import is regulated by a nuclear localization signal and nuclear export signals. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2009]

DRG1 (HGNC:3029): (developmentally regulated GTP binding protein 1) Enables several functions, including GTPase activity; identical protein binding activity; and potassium ion binding activity. Involved in positive regulation of microtubule polymerization and regulation of mitotic spindle assembly. Located in cytosol and nuclear body. Part of polysome.
