Short term-responses to environmental stimuli, which can occur rapidly and are usually reversible, most often result from modification of existing proteins. The long-term response, are usually the result of changes in the transcription of genes. Extracellular signals that induce long-term responses to affect many aspects of cell function; division, differentiation, and even communication with other cells. Alterations in these signaling pathways cause many human diseases including cancer, diabetes, and immune defects. In order to illustrate the variety of mechanisms used to activate key transcription factors, the eight classes of cell surface receptors and the intracellular signal pathways that they activate area important.
Book: Essay Database. In biological membranes the signal sensing and transmittal is initiated by the interaction of a chemical or physical stimulation with a specific membrane receptor which, in bend, becomes activated and initiates a concatenation of intracellular reactions that result in transition of mark protein activity. G-Protein Conjugate Receptors are a superfamily of such membrane proteins that transmit a signal by matching to heterotrimeric-binding proteins, which consist of three fractional monetary units. Rhodopsin is a member of GPCRs superfamily which is pharmacologically of import.
The attributes e, f, g are flexible and the d is decision attribute. We will get the action rules when the decision attribute changes from d2 to d1. This should be done using LERS algorithm.
