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).[6]

Clinical significance

LEF1 is highly overexpressed and associated with disease progression and poor prognosis in B-cell chronic lymphocytic leukemia[7] and other kinds of malignancies like colorectal cancer.[8] It is also a promising potential drug target.[9]

Interactions

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

• ALX4,[10]
• AML-1,[11]
• CTNNB1,[12][13][14][15]
• EP300,[16]
• MITF[17]
• PIAS4,[18]
• SMAD2,[15] and
• SMAD3.[15]
