ZEB1
| View/Edit Human | View/Edit Mouse |
Zinc finger E-box-binding homeobox 1 is a protein that in humans is encoded by the ZEB1 gene.[3][4][5]
ZEB1 (previously known as TCF8) encodes a zinc finger and homeodomain transcription factor that represses T-lymphocyte-specific IL2 gene expression by binding to a negative regulatory domain 100 nucleotides 5-prime of the IL2 transcription start site.[5][6] ZEB1 and its mammalian paralog ZEB2 belongs to the Zeb family within the ZF (zinc finger) class of homeodomain transcription factors. ZEB1 protein has 7 zinc fingers and 1 homeodomain.[7] The structure of the homeodomain shown on the right.
Clinical significance
Mutations of the gene are linked to posterior polymorphous corneal dystrophy 3. A recent study suggested its contributing role in lung cancer invasiveness and metastasis development.[8]
