They are able to facilitate signals that allow for communication between cells and communication within cells. What is a ligand in biology? A ligand in biology is a molecule that can bind to a receptor. This causes a change in cell signaling, and ultimately, cell behavior or structure....
What is a Ligand? Ligandsare small molecules that transmit signals between or within cells. They work by binding to cellular proteins called receptors. Once a ligand binds, the receptor sends additional signals to other parts of the cell. There are two types of ligands: intracellular ligands and...
activator- (biology) any agency bringing about activation; a molecule that increases the activity of an enzyme or a protein that increases the production of a gene product in DNA transcription substance- the real physical matter of which a person or thing consists; "DNA is the substance of our...
Inbiochemistry, KDrefers to the dissociation constant. It is a type of equilibrium constant that measures the propensity of the dissociation of a complex molecule into its subcomponents. It describes how tightly a ligand binds to a particular protein, or at which point the salt dissociates into...
this novel method and provides comparable prediction performance compared with existing methods for the prediction of the oxidation states of cysteines in ... WB Song - 《Journal of Theoretical Biology》 被引量: 4发表: 2004年 Ligand Control of Oxidation and Crystallographic Disorder in the Isolation...
The lack of CD6 domain crystal structure has limited the characterization of the binding sites for the interacting molecules. The interaction between CD6 and its ligand, activated leukocyte-cell adhesion molecule (ALCAM)/CD166, through the membrane-proximal SRCR3 domain, has low affinity and ...
A large meta-analysis, including 20 clinical trials, recently reported on the benefit of 5 years of tamoxifen according to ER and PgR levels as measured by the ligand-binding assay. For women with tumors having <10 fmol ER/mg protein, no evidence of benefit was apparent, whereas for those...
gastrulation- the process in which a gastrula develops from a blastula by the inward migration of cells glycogenesis- the formation in animals of glycogen from glucose growing,growth,ontogenesis,ontogeny,maturation,development- (biology) the process of an individual organism growing organically; a purel...
Apicidin, a histone deacetylase inhibitor, induces apoptosis and Fas/Fas ligand expression in human acute promyelocytic leukemia cells. We previously reported that apicidin arrested human cancer cell growth through selective induction of p21(WAF1/Cip1). In this study, the apoptotic potentia... SH Kw...
These essays by leading scientists and philosophers address conceptuaissues that arise in the theory and practice of evolutionary biology. The thiredition of this widely used anthology has been substantially revised and updatedFour new s...
