Type: Binary Subtype: Pre‑translational | |||||||
Pre-translational mechanisms such as alternative splicing, alternative promoter-usage and/or RNA editing result in inclusion or removal of exons that contain an entire or partial motif. | |||||||
FBXW7_HUMAN | TRG_NES_CRM1_2 | 19 | 26 | Alternative splicing removes the nuclear export signal (NES) of Isoform Archipelago beta of F-box/WD repeat-containing protein 7 (FBXW7), abrogating binding to Exportin-1 (XPO1) and export from nucleus. The presence of the NES produces an isoform with a cytoplasmic localisation. The two other isoforms of FBXW7 localise to the nucleus and the nucleolus, respectively. | |||
SMAD4_HUMAN | TRG_NES_CRM1_2 | 142 | 149 | Alternative splicing removes the nuclear export signal (NES) motif of Mothers against decapentaplegic homolog 4 (SMAD4), thereby inhibiting binding to Exportin-1 (XPO1) and export from the nucleus. A splice variant lacking the NES does not shuttle back and forth between nucleus and cytosol. At present, this particular splice variant is not annotated in UniProtKB. | |||
MDM2_HUMAN | TRG_NES_CRM1_2 | 190 | 202 | Alternative splicing removes the nuclear export signal (NES) of E3 ubiquitin-protein ligase Mdm2 (MDM2), abrogating binding to Exportin-1 (XPO1). | |||
NF2L1_HUMAN | TRG_NES_CRM1_2 | 251 | 259 | Alternative splicing removes the nuclear export signal (NES) of Nuclear factor erythroid 2-related factor 1 (NFE2L1), abrogating binding to Exportin-1 (XPO1). Only the full-length variant of NFE2L1 (Isoform 1 of Nuclear factor erythroid 2-related factor 1 (NFE2L1)) contains an NES and shows cytoplasmic localisation. The two other naturally occuring isoforms (of which at present only 1 is annotated in UniProtKB) lack the NES and show exclusive nuclear staining. |
