A tetramer (/ ˈ t ɛ t r ə m ər /) (tetra-, "four" + -mer, "parts") is an oligomer formed from four monomers or subunits. The associated property is called tetramery . An example from inorganic chemistry is titanium methoxide with the empirical formula Ti(OCH 3 ) 4 , which is tetrameric in solid state and has the molecular formula Ti 4 (OCH ...
The formation of the sorbitol dehydrogenase tetramer from its monomers via dimers. A tetrameric protein is a protein with a quaternary structure of four subunits (tetrameric). Homotetramers have four identical subunits (such as glutathione S-transferase ), and heterotetramers are complexes of different subunits.
This usually implies that the complex consists of different oligomerisation interfaces. For example, a tetrameric protein may have one four-fold rotation axis, i.e. point group symmetry 4 or C 4 . In this case the four interfaces between the subunits are identical.
Pentamers consist of five MHC-peptide headgroups, arranged in a planar configuration so that, unlike MHC tetramers, all of the headgroups can contact the CD8+ T cell. The headgroups are connected via flexible linkers to a coiled-coil multimerization domain, which in turn is connected to five fluorescent or biotin tags.
A tetramer assay (also known as a tetramer stain) is a procedure that uses tetrameric proteins to detect and quantify T cells that are specific for a given antigen within a blood sample. [1] The tetramers used in the assay are made up of four major histocompatibility complex (MHC) molecules, which are found on the surface of most cells in the ...
Hemoglobin A is the most common adult form of hemoglobin and exists as a tetramer containing two alpha subunits and two beta subunits (α2β2). [3] Hemoglobin A2 (HbA2) is a less common adult form of hemoglobin and is composed of two alpha and two delta-globin subunits. This hemoglobin makes up 1-3% of hemoglobin in adults. [4]

In chemistry and biochemistry, an oligomer (/ ə ˈ l ɪ ɡ ə m ər / ⓘ) is a molecule that consists of a few repeating units which could be derived, actually or conceptually, from smaller molecules, monomers. [1] [2] [3] The name is composed of Greek elements oligo-, "a few" and -mer, "parts". An adjective form is oligomeric. [3]
