In the two- and three-domain systems, this puts them into a separate domain. There is a great deal of diversity in the domain Bacteria. That diversity is further confounded by the exchange of genes between different bacterial lineages. The occurrence of duplicate genes between otherwise distantly-related bacteria makes it nearly impossible to ...
A Link domain or Link module, also known as Xlink domain (X for extracellular), is a protein domain that binds to hyaluronic acid. [1] It is important in blood cell migration and apoptosis . [ 2 ] The link domain is found in some extracellular proteins in vertebrates such as the hyalectans . [ 3 ]
LIM domains are protein structural domains, composed of two contiguous zinc fingers, separated by a two-amino acid residue hydrophobic linker. [1] The domain name is an acronym of the three genes in which it was first identified (LIN-11, Isl-1 and MEC-3). [ 2 ]
The three-domain system adds a level of classification (the domains) "above" the kingdoms present in the previously used five- or six-kingdom systems.This classification system recognizes the fundamental divide between the two prokaryotic groups, insofar as Archaea appear to be more closely related to eukaryotes than they are to other prokaryotes – bacteria-like organisms with no cell nucleus.
Unique factorization domain, an integral domain in which every non-zero element can be written as a product of irreducible elements in essentially a unique way; Domain of a function, the set of input values for which the (total) function is defined Domain of definition of a partial function; Natural domain of a partial function
In molecular biology, the FERM domain (F for 4.1 protein, E for ezrin, R for radixin and M for moesin) is a widespread protein module involved in localising proteins to the plasma membrane. [1] FERM domains are found in a number of cytoskeletal -associated proteins that associate with various proteins at the interface between the plasma ...
PDZ is an acronym derived from the names of the first proteins in which the domain was observed. Post-synaptic density protein 95 (PSD-95) is a synaptic protein found only in the brain. [ 7 ] Drosophila disc large tumor suppressor (Dlg1) and zona occludens 1 (ZO-1) both play an important role at cell junctions and in cell signaling complexes. [ 9 ]
