Non-phosphorylated 4EBP1 competes with EIF4G1\/EIF4G3 to interact with EIF4E. 4EBP1 is phosphorylated in response to various signals including insulin signaling, resulting in its dissociation from eIF4E and activation of mRNA translation. 4EBP1 has a role in progression of breast neoplasms through cell signaling.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAlternative names\u003c\/strong\u003e: 4E-BP1;4EBP1;BP-1;EIF4EBP1;Eukaryotic Translation Initiation Factor 4E-Binding Protein 1;PHAS-I;Phosphorylated Heat- and Acid-Stable Protein Regulated by Insulin 1;eIF4E-Binding Protein 1\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cspan class=\"bhp-cat-pill\"\u003eE. coli Expression\u003c\/span\u003e\n\u003cp\u003eThis recombinant protein is produced using a validated E. coli expression system and supplied as lyophilized powder with N-His affinity tag.
