Lymphoid enhancer-binding factor 1 (LEF1) is a protein that in humans is encoded by the LEF1 gene.[5]
Contents
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] It is also a promising potential drug target.[8]
Interactions
Lymphoid enhancer-binding factor 1 has been shown to interact with:
- ALX4,[9]
- AML-1,[10]
- CTNNB1,[11][12][13][14]
- EP300,[15]
- MITF[16]
- PIAS4,[17]
- SMAD2,[14] and
- SMAD3.[14]
