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

Function

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) enhancer and confers maximal enhancer activity. LEF1 belongs to a family of regulatory proteins that share homology with high mobility group protein-1 (HMG1).^[2]

Clinical significance

LEF1 is highly overexpressed and associated with disease progression and poor prognosis in B-cell chronic lymphocytic leukemia.^[3] It is also a promising potential drug target.^[4]

Interactions

Lymphoid enhancer-binding factor 1 has been shown to interact with:

• ALX4,^[5]
• AML-1,^[6]
• CTNNB1,^{[7][8][9][10]}
• EP300,^[11]
• MITF^[12]
• PIAS4,^[13]
• SMAD2,^[10] and
• SMAD3.^[10]
