Alternate use of an in-frame upstream non-AUG (CUG) translation initiation codon, and a downstream AUG codon, results in two isoforms. While the long isoform (22 kDa) acts as an activator, the short isoform (14 kDa) has been shown to repress gamma-globin gene expression. This gene is located in an intron of the FBXL13 gene on the opposite strand.

The complex binds to the stage selector element (SSE) in the proximal gamma-globin promoter. In contrast, isoform 2 acts as a repressor of gamma-globin gene expression by preventing NFE2 and RNA polymerase II recruitment to the promoter.,PTM:Acetylation at Lys-43 prolongs the protein half-life by preventing ubiquitin-mediated degradation and reduces the interaction between NF-E4 and HDAC1, potentially maximizing the activating ability of the factor at the gamma-promoter.,PTM:Ubiquitinated; leading to its degradation by the proteasome. Acetylation at Lys-43 prevents ubiquitination.,sequence caut\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSpecies:\u003c\/b\u003e Human;Rat;Mouse;\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRange:\u003c\/b\u003e IHC;IF;WB\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eProtein:\u003c\/b\u003e NF-E4\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDA:\u003c\/b\u003e 19kD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Upingbio","offers":[{"title":"100UL","offer_id":50690760933656,"sku":"YP-Ab-10854-100UL","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/images_8e9b44f3-c88a-4e8f-9466-e0a953fb616d.png?v=1758612254","url":"https:\/\/danabiosci.com\/products\/yp-ab-10854-100ul","provider":"Dana Bioscience","version":"1.0","type":"link"}
