Glycoproteins

The terms glycan and polysaccharide are defined by IUPAC as synonyms meaning "compounds consisting of a large number of monosaccharides linked glycosidically".

Neuregulins or neuroregulins are a family of four structurally related proteins that are part of the EGF family of proteins.

Luteinizing hormone (LH, also known as lutropin and sometimes lutrophin) is a hormone produced by gonadotropic cells in the anterior pituitary gland.

Thyroid-stimulating hormone (also known as thyrotropin, thyrotropic hormone, TSH, or hTSH for human TSH) is a pituitary hormone that stimulates the thyroid gland to produce thyroxine (T4), and then triiodothyronine (T3) which stimulates the metabolism of almost every tissue in the body.

Not to be confused with Osteocalcin, Osteonectin or Osteoprotegerin (OPG).

In molecular biology, CD4 (cluster of differentiation 4) is a glycoprotein found on the surface of immune cells such as T helper cells, monocytes, macrophages, and dendritic cells.

Human chorionic gonadotropin (hCG) is a hormone produced by the placenta after implantation.

Enteropeptidase (also called enterokinase) is an enzyme produced by cells of the duodenum and involved in human and animal digestion.

Follicle-stimulating hormone (FSH) is a gonadotropin, a glycoprotein polypeptide hormone.

CD1 (cluster of differentiation 1) is a family of glycoproteins expressed on the surface of various human antigen-presenting cells.

Glycoproteins are proteins that contain oligosaccharide chains (glycans) covalently attached to polypeptide side-chains.

The major histocompatibility complex (MHC) is a set of cell surface proteins essential for the acquired immune system to recognize foreign molecules in vertebrates, which in turn determines histocompatibility.

Avidin is a tetrameric biotin-binding protein produced in the oviducts of birds, reptiles and amphibians and deposited in the whites of their eggs.

A glycophorin is a sialoglycoprotein of the membrane of a red blood cell.

Envelope glycoprotein GP120 (or gp120) is a glycoprotein exposed on the surface of the HIV envelope.

Peanut agglutinin (PNA) is plant lectin protein derived from the fruits of Arachis hypogaea.

Glycophorin C (GYPC; CD236/CD236R; glycoprotein beta; glycoconnectin; PAS-2') plays a functionally important role in maintaining erythrocyte shape and regulating membrane material properties, possibly through its interaction with protein 4.

Gp41 also known as glycoprotein 41 is a subunit of the envelope protein complex of retroviruses, including human immunodeficiency virus (HIV).

Agrin is a large proteoglycan whose best-characterised role is in the development of the neuromuscular junction during embryogenesis.

(Not to be confused with Osteocalcin or Osteopontin.) Osteonectin (ON) also known as secreted protein acidic and rich in cysteine (SPARC) or basement-membrane protein 40 (BM-40) is a protein that in humans is encoded by the SPARC gene.

Orosomucoid (ORM) or alpha-1-acid glycoprotein (α1AGp, AGP or AAG) is an acute phase (acute phase protein) plasma alpha-globulin glycoprotein and is modulated by two polymorphic genes.

Androgen-binding protein (ABP) is a glycoprotein (beta-globulin) produced by the Sertoli cells in the seminiferous tubules of the testis that binds specifically to testosterone (T), dihydrotestosterone (DHT), and 17-beta-estradiol.

Nuclear pore glycoprotein-210 (gp210) is an essential trafficking regulator in the eukaryotic nuclear pore complex.

Recombinant factor VIIa (rFVIIa) is a form of blood factor VII that has been manufactured via recombinant technology.
