Protein-coding gene in the species Homo sapiens
Lymphoid enhancer-binding factor 1 (LEF1 ) is a protein that in humans is encoded by the LEF1 gene .[5] TCF/LEF ) family.
Function [ edit ] 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 [ edit ] LEF1 is highly overexpressed and associated with disease progression and poor prognosis in B-cell chronic lymphocytic leukemia [7] colorectal cancer .[8] [9]
Interactions [ edit ] Lymphoid enhancer-binding factor 1 has been shown to interact with:

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
