Lymphoid enhancer-binding factor 1 is a protein that in humans is encoded by the LEF1 gene.[1]

Lymphoid enhancer-binding factor-1 (LEF1) is a 48-kD nuclear protein that is expressed in pre-B and T cells. It binds to a functionally important site in the T-cell receptor-alpha (TCRA; MIM 186880) enhancer and confers maximal enhancer activity. LEF1 belongs to a family of regulatory proteins that share homology with high mobility group protein-1 (HMG1; MIM 163905).[supplied by OMIM][2]

Interactions

Lymphoid enhancer-binding factor 1 has been shown to interact with Beta-catenin,[3][4][5][6] PIAS4,[7] ALX4,[8] EP300,[9] Mothers against decapentaplegic homolog 3,[6] Microphthalmia-associated transcription factor[10] and Mothers against decapentaplegic homolog 2.[6]
