TermDefinition
Alternative Splicing a regulated process during gene expression that results in a single gene coding for multiple proteins
Arachiodonic acid a fatty acid and a precursor that is metabolized by various enzymes to a wide range of biologically and clinically important eicosanoids involved in cellular signaling
Arrestins Proteins that bind to a receptor to block further signaling; they target receptors for internalization; they redirect signaling to alternative pathways
Autophosphrylation a process by which kinase proteins phosphorylate themselves enzymatically
Calthrin a plasma membrane surface protein that plays a major role in endocytosis of vesicles and internalization of receptors
Coactivators proteins that stimulate gen expression by binding to a transcription factor that has attached to a DNA
Cytokines small proteins produced by cells of the immune system that act as hormones and affect communications between body cells
G-protein cell membrane proteins that are attached to cell surface receptors and upon stimulation of the receptor by a signaling molecule bind to GTP to form an active complex which mediates an intracellular event
G-protein coupled kinases a family of proteins that regulate the activity of G protein-coupled receptors (GPCRs) by phosphorylating specific amino acids to prevent reactivation of the signaling pathway
Globulins a family of proteins in blood that are produced in the liver and can act as carriers of hormones
Half life of a hormone the amount of time it takes for a hormone concentration in blood to be reduced by half of its original concentration
Homodimers a molecule composed of paired identical proteins
Hypophysis another word for the pituitary gland (anterior pituitary = adenohypophysis; posterior pituitary = neurohypophysis)
Hypothalamo-pituitary axis hypothalamus together with the pituitary gland
Iodothyronines any of the iodinated derivatives of thyroid hormones
Regulatory System any stimulus-response mechanism to allow organisms to sense and respond to changes in many different environmental conditions
Transcortin an alpha-globulin that binds and transports biologically active cortisol hormone in plasma
Transcription factors proteins that control which genes are turned on and off in the genome, binds to specific DNA sequence controlling the transcription of DNA to mRNA
Transduction the process of converting a signal into another form
Tyrosine kinases an enzyme that can transfer a phosphate group from ATP to a protein in a cell
