Krueppel-like factor 6 is a protein that in humans is encoded by the KLF6 gene. [5]
It is a tumor suppressor gene. [6]
This gene encodes a nuclear protein that has three zinc fingers at the end of its C-terminal domain, a serine/threonine-rich central region, and an acidic domain lying within the N-terminal region. The zinc fingers of this protein are responsible for the specific DNA binding with the guanine-rich core promoter elements. The central region might be involved in activation or posttranslational regulatory pathways, and the acidic N-terminal domain might play an important role in the process of transcriptional activation. It is capable of activating transcription approximately 4-fold either on homologous or heterologous promoters. The DNA binding and transcriptional activity of this protein, in conjunction with its expression pattern, suggests that this protein may participate in the regulation and/or maintenance of the basal expression of pregnancy-specific glycoprotein genes and possibly other TATA box-less genes. Two transcript variants encoding the same protein have been found for this gene. [7]
KLF6 has been shown to interact with Sp1 transcription factor. [8]
In molecular biology, a transcription factor (TF) is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific DNA sequence. The function of TFs is to regulate—turn on and off—genes in order to make sure that they are expressed in the desired cells at the right time and in the right amount throughout the life of the cell and the organism. Groups of TFs function in a coordinated fashion to direct cell division, cell growth, and cell death throughout life; cell migration and organization during embryonic development; and intermittently in response to signals from outside the cell, such as a hormone. There are 1500-1600 TFs in the human genome. Transcription factors are members of the proteome as well as regulome.
EGR-1 also known as ZNF268 or NGFI-A is a protein that in humans is encoded by the EGR1 gene.
Zinc finger protein GLI1 also known as glioma-associated oncogene is a protein that in humans is encoded by the GLI1 gene. It was originally isolated from human glioblastoma cells.
In molecular genetics, the Krüppel-like family of transcription factors (KLFs) are a set of eukaryotic C2H2 zinc finger DNA-binding proteins that regulate gene expression. This family has been expanded to also include the Sp transcription factor and related proteins, forming the Sp/KLF family.
Krüppel is a gap gene in Drosophila melanogaster, located on the 2R chromosome, which encodes a zinc finger C2H2 transcription factor. Gap genes work together to establish the anterior-posterior segment patterning of the insect through regulation of the transcription factor encoding pair rule genes. These genes in turn regulate segment polarity genes. Krüppel means "cripple" in German, named for the crippled appearance of mutant larvae, who have failed to develop proper thoracic and anterior segments in the abdominal region. Mutants can also have abdominal mirror duplications.
Transcription factor E2F1 is a protein that in humans is encoded by the E2F1 gene.
CCAAT/enhancer-binding protein beta is a protein that in humans is encoded by the CEBPB gene.
Tripartite motif-containing 28 (TRIM28), also known as transcriptional intermediary factor 1β (TIF1β) and KAP1, is a protein that in humans is encoded by the TRIM28 gene.
Kruppel-like factor 4 is a member of the KLF family of zinc finger transcription factors, which belongs to the relatively large family of SP1-like transcription factors. KLF4 is involved in the regulation of proliferation, differentiation, apoptosis and somatic cell reprogramming. Evidence also suggests that KLF4 is a tumor suppressor in certain cancers, including colorectal cancer. It has three C2H2-zinc fingers at its carboxyl terminus that are closely related to another KLF, KLF2. It has two nuclear localization sequences that signals it to localize to the nucleus. In embryonic stem cells (ESCs), KLF4 has been demonstrated to be a good indicator of stem-like capacity. It is suggested that the same is true in mesenchymal stem cells (MSCs).
PRKC apoptosis WT1 regulator protein, or Prostate apoptosis response-4, is a tumor-suppressor protein coded for in the human by the PAWR gene, that induces apoptosis in cancer cells, but not in normal cells.
Homeobox protein Nkx-3.1, also known as NKX3-1, NKX3, BAPX2, NKX3A and NKX3.1 is a protein that in humans is encoded by the NKX3-1 gene located on chromosome 8p. NKX3-1 is a prostatic tumor suppressor gene.
Krueppel-like factor 5 is a protein that in humans is encoded by the KLF5 gene.
Transcription factor Sp4 is a protein that in humans is encoded by the SP4 gene.
Krueppel-like factor 11 is a protein that in humans is encoded by the KLF11 gene.
Zinc finger protein 10 is a protein that in humans is encoded by the ZNF10 gene.
Krueppel-like factor 8 is a protein that in humans is encoded by the KLF8 gene. KLF8 belongs to the family of KLF protein. KLF8 is activated by KLF1 along with KLF3 while KLF3 represses KLF8.
Transcription factor AP-2 gamma also known as AP2-gamma is a protein that in humans is encoded by the TFAP2C gene. AP2-gamma is a member of the activating protein 2 family of transcription factors.
Scott L. Friedman is an American scientist, professor and physician who works in the field of hepatology. Friedman has conducted pioneering research into the underlying causes of scarring, or fibrosis, associated with chronic liver disease, by characterizing the key fibrogenic cell type, the hepatic stellate cell His laboratory has also discovered a novel tumor suppressor gene, KLF6 that is inactivated in a number of human cancers including primary liver cancer. Friedman is the Fishberg Professor of Medicine, and Chief of the Division of Liver Diseases, Mount Sinai School of Medicine in New York. Friedman has two children, a son, Leor Friedman, and a daughter, Yael Friedman.
The retinoblastoma protein is a tumor suppressor protein that is dysfunctional in several major cancers. One function of pRb is to prevent excessive cell growth by inhibiting cell cycle progression until a cell is ready to divide. When the cell is ready to divide, pRb is phosphorylated, inactivating it, and the cell cycle is allowed to progress. It is also a recruiter of several chromatin remodeling enzymes such as methylases and acetylases.
Krüppel-like factor 15 is a protein that in humans is encoded by the KLF15 gene in the Krüppel-like factor family. Its former designation KKLF stands for kidney-enriched Krüppel-like factor.
