Dictionary » R » Receptor



1. A molecular structure within a cell or on the surface characterised by selective binding of a specific substance and a specific physiologic effect that accompanies the binding, for example, cell surface receptors for peptide hormones, neurotransmitters, antigens, complement fragments and immunoglobulins and cytoplasmic receptors for steroid hormones.

2. A sensory nerve terminal that responds to stimuli of various kinds. An organ having nerve endings (in the skin or viscera or eye or ear or nose or mouth) that respond to stimulation.A cellular structure that is postulated to exist in order to mediate between a chemical agent that acts on nervous tissue and the physiological response.An organ having nerve endings (in the skin or viscera or eye or ear or nose or mouth) that respond to stimulation.A type of cell or organ that is capable of detecting the presence of a particular stimulus, which in turn, will bring about a response in the organism due to the presence / absence / change in concentration of the stimulus.

What makes dominant allele dominant?

... peptide is too short to do its work. Or you can have change of a crucial residue to turn off your protein, like in case of Asp to Asn mutations in receptor which impair its ability to transfer phosphates and thus signal the binding. Or you could change the post-translational modification and thus ...

Cell signalling inhibitors

Hi guys, Can you please list for me some cell signalling inhibitors for C. elegans (or generic) and tell me the enzyme or receptor that is inhibited? (Preferably for tyrosine kinase, G-protein, JAK/STAT and Phosphatidylinositol 3-kinase) Thanks :D

Science versus a job as a "scientist"

... I didn't find too much in your general suggestions that I haven't seen discussed before. Where and when before did you see discussed growth factor receptor inhibitors used to protect normal cells from the toxic side-effects of chemotherapy? Before my article and my links and reference? I think ...
