Adaptor protein - F-box protein - GTP-binding protein - Light-harvesting complex - Membrane transport protein Medical Subject Headings (MeSH) is a huge controlled vocabulary (or metadata system) for the purpose of indexing journal articles and books in the life sciences. ... A representation of the 3D structure of myoglobin, showing coloured alpha helices. ... Carrier proteins are proteins that transport a particular substance in the blood or across the cell membrane. ... An adaptor protein is a protein which is accessory to main proteins in signal transduction. ... F-box proteins are proteins containing at least one F-box motif, a protein structural motif of about 50 amino acids that mediates protein-protein interactions. ... G-proteins, short for guanine nucleotide binding proteins, are a family of proteins involved in second messenger cascades. ... A light-harvesting complex is one or more polypeptide chains containing photosynthetic pigments, which surrounds a photosynthetic reaction centre and focuses light inward toward its core. ... A membrane transport protein is a protein involved in the movement of a chemical such as an ion or another protein across a biological membrane. ...

Calcium-binding protein - Calmodulin-binding proteins - Ceruloplasmin - Iron-binding proteins - Retinol binding protein - Transferrin receptor - Transcobalamins Calcium-binding proteins are proteins that participate in calcium cell signalling pathways by binding to Ca2+. The most ubiquitous Ca2+-sensing protein, found in all eukaryotic organisms including yeasts, is calmodulin. ... Calmodulin-binding proteins are, as their name implies, proteins which bind calmodulin. ... Ceruloplasmin Ceruloplasmin (or caeruloplasmin), officially known as ferroxidase or iron(II):oxygen oxidoreductase, is a copper transport protein found in the blood. ... Retinol, the dietary form of vitamin A, is a fat-soluble, antioxidant vitamin important in vision and bone growth. ... Transferrin receptor is a carrier protein for transferrin. ... Transcobalamins are carrier proteins which bind cyanocobalamin (B12). ...

Follistatin - Growth hormone binding protein - Insulin-like growth factor binding protein - Neurophysins (Neurophysin I, II) - Sex hormone binding globulin/Androgen binding protein - Thyroxine-binding globulin - Transcortin - Transthyretin Follistatin is a single chain gonadal protein that inhibits Follicle-stimulating hormone release. ... The Insulin-like growth factor binding protein serves as a carrier protein for Insulin-like growth factor 1. ... Neurophysins are carrier proteins for the hormones generated in the hypothalamus and distributed from the posterior pituitary. ... Neurophysin I is a carrier protein with a size of 10 KDa and containing 90 to 97 aminoacids that transports neurohypophysial hormones along axons, from the hypothalamus to the posterior lobe of the pituitary. ... Sex hormone binding globulin (SHBG) is a glycoprotein that binds to sex hormones, specifically testosterone and estradiol. ... Androgen binding protein is a protein produced by the Sertoli cells in the seminiferous tubules that binds androgen hormones like testosterone. ... Thyroxine-binding globulin (TBG) or transthyretin is the major binding protein of thyroid hormones in the bloodstream. ... Transcortin, also corticosteroid binding protein or CBG, is an alpha-globulin that has high affinity for binding cortisol. ... Transthyretin (TTR) is a serum and cerebrospinal fluid carrier of the thyroid hormone thyroxine (T4). ...
