TNKS
Tankyrase, also known as tankyrase 1, is an enzyme that in humans is encoded by the ''TNKS'' gene. It inhibits the binding of TERF1 to telomeric DNA. Tankyrase attracts substantial interest in cancer research through its interaction with AXIN1 and AXIN2, which are negative regulators of pro-oncogenic β-catenin signaling. Importantly, activity in the β-catenin destruction complex can be increased by tankyrase inhibitors and thus such inhibitors are a potential therapeutic option to reduce the growth of β-catenin-dependent cancers. Description Tankyrase-1 is a poly-ADP-ribosyltransferase involved in various processes such as Wnt signaling pathway, telomere length and vesicle trafficking. Acts as an activator of the Wnt signaling pathway by mediating poly-ADP-ribosylation (PARylation) of AXIN1 and AXIN2, 2 key components of the beta-catenin destruction complex: poly-ADP-ribosylated target proteins are recognized by RNF146, which mediates their ubiquitination and subsequent degr ...

TERF1
Telomeric repeat-binding factor 1 is a protein that in humans is encoded by the ''TERF1'' gene. Gene The human TERF1 gene is located in the chromosome 8 at 73,921,097-73,960,357 bp. Two transcripts of this gene are alternatively spliced products. The TERF1 gene is also known as TRF, PIN2 (Proteinase Inhibitor 2), TRF1, t-TRF1 and h-TRF1-AS.

ADP-ribosylation
ADP-ribosylation is the addition of one or more ADP-ribose moieties to a protein. It is a reversible post-translational modification that is involved in many cellular processes, including cell signaling, DNA repair, gene regulation and apoptosis. Improper ADP-ribosylation has been implicated in some forms of cancer. It is also the basis for the toxicity of bacterial compounds such as cholera toxin, diphtheria toxin, and others. History The first suggestion of ADP-ribosylation surfaced during the early 1960s. At this time, Pierre Chambon and coworkers observed the incorporation of ATP into hen liver nuclei extract. After extensive studies on the acid insoluble fraction, several different research laboratories were able to identify ADP-ribose, derived from NAD+, as the incorporated group. Several years later, the enzymes responsible for this incorporation were identified and given the name poly(ADP-ribose)polymerase. Originally, this group was thought to be a linear sequence of ...

MCL1
Induced myeloid leukemia cell differentiation protein Mcl-1 is a protein that in humans is encoded by the ''MCL1'' gene. Function The protein encoded by this gene belongs to the Bcl-2 family. Alternative splicing occurs at this locus and two transcript variants encoding distinct isoforms have been identified. The longer gene product (isoform 1) enhances cell survival by inhibiting apoptosis while the alternatively spliced shorter gene product (isoform 2) promotes apoptosis and is death-inducing. The protein MCL1 has a very short biological half-life of only 20–30 minutes. The loss of MCL1 has a more dramatic impact than the loss of any other anti-apoptotic member of the Bcl-2 family. Loss of the ''Mcl-1'' gene results in embryo death when the embryo is only around 3.5 days old, before it has even implanted. Conditional deletion of ''Mcl-1'' depletes a wide variety of cells, including hematopoietic stem cells, B cell–committed progenitors, T cell–committed progenitors, ...

Enzyme
An enzyme () is a protein that acts as a biological catalyst by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different molecules known as product (chemistry), products. Almost all metabolism, metabolic processes in the cell (biology), cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme, pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts include Ribozyme, catalytic RNA molecules, also called ribozymes. They are sometimes descr ...

HEPACAM
display Gene HEPACAM*, named based on its original site of identification - hepatocytes and the nature of its protein product - a cell adhesion molecule (CAM), was first discovered and characterised in human liver. The gene encodes a protein of 416 amino acids, designated as hepaCAM**, which is a new member of the immunoglobulin superfamily of cell adhesion molecules (IgSF CAM). The main biological functions of hepaCAM include a) modulating cell-matrix adhesion and migration, and b) inhibiting cancer cell growth. (Note: *HEPACAM, gene name; **hepaCAM, protein name) Discovery Through differential screening of gene expression, over 200 genes were found to be either up- or down-regulated in a hepatocellular carcinoma patient. These genes were subsequently evaluated against a panel of human HCC specimens, leading to the identification of a novel gene HEPN1. Based on the sequence of HEPN1, the new gene HEPACAM was then isolated and characterised. Characteristics and functions Str ...

SLC2A4
Glucose transporter type 4 (GLUT4), also known as solute carrier family 2, facilitated glucose transporter member 4, is a protein encoded, in humans, by the ''SLC2A4'' gene. GLUT4 is the insulin-regulated glucose transporter found primarily in adipose tissues and striated muscle (skeletal and cardiac). GLUT4 is distinctive because it is predominantly stored within intracellular vesicles, highlighting the importance of its trafficking and regulation as a central area of research. The first evidence for this glucose transport protein was provided by David James in 1988. The gene that encodes GLUT4 was cloned and mapped in 1989. At the cell surface, GLUT4 permits the facilitated diffusion of circulating glucose down its concentration gradient into muscle and fat cells. Once within cells, glucose is rapidly phosphorylated by glucokinase in the liver and hexokinase in other tissues to form glucose-6-phosphate, which then enters glycolysis or is polymerized into glycogen. Glucose-6-p ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
