background:
This gene encodes a zinc finger transcription factor. The encoded protein likely plays a role in transcriptional repression of interleukin 2. Mutations in this gene have been associated with posterior polymorphous corneal dystrophy-3 and late-onset Fuchs endothelial corneal dystrophy. Alternatively spliced transcript variants encoding different isoforms have been described.[provided by RefSeq, Mar 2010]
Function:
Acts as a transcriptional repressor. Inhibits interleukin-2 (IL-2) gene expression. Enhances or represses the promoter activity of the ATP1A1 gene depending on the quantity of cDNA and on the cell type. Represses E-cadherin promoter and induces an epithelial-mesenchymal transition (EMT) by recruiting SMARCA4/BRG1. Represses BCL6 transcription in the presence of the corepressor CTBP1. Positively regulates neuronal differentiation. Represses RCOR1 transcription activation during neurogenesis. Represses transcription by binding to the E box (5'-CANNTG-3'). Promotes tumorigenicity by repressing stemness-inhibiting microRNAs.
Subunit:
Interacts (via N-terminus) with SMARCA4/BRG1.
Subcellular Location:
Nucleus.
Tissue Specificity:
Colocalizes with SMARCA4/BRG1 in E-cadherin-negative cells from established lines, and stroma of normal colon as well as in de-differentiated epithelial cells at the invasion front of colorectal carcinomas (at protein level). Expressed in heart and skeletal muscle, but not in liver, spleen, or pancreas.
DISEASE:
Corneal dystrophy, posterior polymorphous, 3 (PPCD3) [MIM:609141]: A subtype of posterior corneal dystrophy, a disease characterized by alterations of Descemet membrane presenting as vesicles, opacities or band-like lesions on slit-lamp examination and specular microscopy. Affected patient typically are asymptomatic. Note=The disease is caused by mutations affecting the gene represented in this entry.
Corneal dystrophy, Fuchs endothelial, 6 (FECD6) [MIM:613270]: A corneal disease caused by loss of endothelium of the central cornea. It is characterized by focal wart-like guttata that arise from Descemet membrane and develop in the central cornea, epithelial blisters, reduced vision and pain. Descemet membrane is thickened by abnormal collagenous deposition. Note=The disease is caused by mutations affecting the gene represented in this entry.
Similarity:
Belongs to the delta-EF1/ZFH-1 C2H2-type zinc-finger family.
Contains 7 C2H2-type zinc fingers.
Contains 1 homeobox DNA-binding domain.
