protein signal sequence definition: N-terminal, hydrophobic sequences which mediate the attachment of newly translated polypeptide chains to intracellular membranes; in some membrane proteins the signal peptide remains as a permanent anchor, while in secretory proteins it is cleaved.
Signal Peptide definition: The N-terminal sequence of a secreted protein that interacts with a signal recognition particle and is required for transport through the cell membrane.
Signal Peptides definition: Highly hydrophobic amino acid sequences of proteins that must cross through membranes to arrive at their functioning cellular location (such as secreted and membrane proteins). They are 15 to 60 amino acids long and reside at the amino-terminus (leader signal peptides) or internally. By binding to signal recognition particles, these sequences direct nascent protein-ribosome complexes to a membrane where the protein is inserted during translation. Signal peptides direct translational uptake of the protein by various membranes -endoplamic reticulum, mitochondrial, chloroplast, peroxisomal, etc. Leader signal sequences on non-membrane proteins are ultimately removed by specific peptidases.
Signal Detection, Psychological definition: Psychophysical technique that permits the estimation of the bias of the observer as well as detectability of the signal (i.e., stimulus) in any sensory modality. (From APA, Thesaurus of Psychological Index Terms, 8th ed.)
Signal Induction definition: Signal induction is the intercellular or intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (e.g., hormone, neurotransmitter, etc.) is transferred to a receptor molecule through a physical binding interaction that alters the conformational and functional state of the receptor molecule and promotes an alteration in cell function.
Signal Repression definition: Repression of any of several ways in which living cells of an organism communicate with one another, whether by direct contact between cells or by means of chemical signals.
Signal definition: A detectable physical quantity or impulse (e.g., voltage, current, or magnetic field strength).
generation of a signal involved in cell-cell signaling definition: The cellular process by which a physical entity or change in state, a signal, is created that originates in one cell and is used to transfer information to another cell. This process begins with the initial formation of the signal and ends with the mature form and placement of the signal. [GOC:dph]
Sensitivity definition: A measure of the minimum change in an input signal that an instrument can detect.
signal definition: Signal.
