A taxis (from Ancient Greek τάξις (táxis) 'arrangement, order'; [1] pl.: taxes / ˈ t æ k s iː z /) [2] [3] [4] is the movement of an organism in response to a stimulus such as light or the presence of food. Taxes are innate behavioural responses.
The lipid globules contain a complex mixture of carotenoid pigments, which provide the screening function and the orange-red colour, [40] as well as proteins that stabilize the globules. [41] The stigma is located laterally, in a fixed plane relative to the cilia, but not directly adjacent to the basal bodies.
Chemotaxis (from chemo-+ taxis) is the movement of an organism or entity in response to a chemical stimulus. [1] Somatic cells , bacteria , and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment.
C1-inhibitor is the largest member among the serpin superfamily of proteins. It can be noted that, unlike most family members, C1-inhibitor has a 2-domain structure.The C-terminal serpin domain is similar to other serpins, which is the part of C1-inhibitor that provides the inhibitory activity.
These proteins after phosphorylation become activated and allow binding of others enzymes that continue the biochemical cascade. [4] [44] [45] [46] One example of a protein that binds to adaptor proteins and become activated is PLC that is very important in the lymphocyte signal pathways.
"Fixed action pattern" is an ethological term describing an instinctive behavioral sequence that is highly stereotyped and species-characteristic. [1] Fixed action patterns are said to be produced by the innate releasing mechanism, a "hard-wired" neural network, in response to a sign/key stimulus or releaser.
Kinesin is a protein functioning as a molecular biological machine. It uses protein domain dynamics on nanoscales. A protein complex or multiprotein complex is a group of two or more associated polypeptide chains. Protein complexes are distinct from multidomain enzymes, in which multiple catalytic domains are found in a single polypeptide chain ...
The first such methods inferred function based on homologous proteins with known functions (homology-based function prediction). The development of context-based and structure based methods have expanded what information can be predicted, and a combination of methods can now be used to get a picture of complete cellular pathways based on ...
