Sugar signal transduction is an evolutionarily conserved mechanism used by organisms to survive.Sugars have an overwhelming effect on gene expression.In yeast, glucose levels are managed by controlling the mRNA levels of hexose transporters, while in mammals, the response to glucose is more tightly controlled with glucose metabolism and is therefore much more complex.
Olfactory transduction; Sugar signal transduction; Transduction (biophysics), the conveyance of energy from a donor electron to a receptor electron, during which the class of energy changes; Transduction (genetics), the transfer of DNA from one cell to another using a virus or viral vector Tbx18 transduction, a cardiac therapy method
Defined in the narrowest sense, glycobiology is the study of the structure, biosynthesis, and biology of saccharides (sugar chains or glycans) that are widely distributed in nature. [ 1 ] [ 2 ] Sugars or saccharides are essential components of all living things and aspects of the various roles they play in biology are researched in various ...
The diagram above depicts the signal transduction pathway of the sweet taste. Object A is a taste bud, object B is one taste cell of the taste bud, and object C is the neuron attached to the taste cell. I. Part I shows the reception of a molecule. 1. Sugar, the first messenger, binds to a protein receptor on the cell membrane. II.
Signal transduction is a mechanism in which the cell responds to a signal from the environment by activating several proteins and enzymes that will give a response to the signal. Feedback mechanism might involve negative and positive feedbacks. In the negative feedback, the pathway is inhibited and the result of the transduction pathway is ...

Two main signal transduction mechanisms have been identified, via nuclear receptors, or via transmembrane receptors. In the first one, first messenger cross through the cell membrane, binding and activating intracellular receptors localized at nucleus or cytosol , which then act as transcriptional factors regulating directly gene expression.
The signal transduction component labeled as "MAPK" in the pathway was originally called "ERK," so the pathway is called the MAPK/ERK pathway. The MAPK protein is an enzyme, a protein kinase that can attach phosphate to target proteins such as the transcription factor MYC and, thus, alter gene transcription and, ultimately, cell cycle progression.
