Fibronectin is a dimer, whereas tenascin is a hexamer. Often fibronectin and tenascin are colocalized in tissues, but the occurrence of tenascin is much more restricted when compared with fibronectin. Tenascin is transiently expressed in many developing organs such as connective tissues, the ...
Poly-A is a repetitive sequence of adenine nucleotides added posttranscriptional to the 3’-end of a eukaryotic mRNA molecule.
Polyadenylation requires at least two specific signals encoded by the preRNA: (1)the poly(A) signal, which is encoded by a conserved AAUAAA hexamerand is rarely located more than 23 nucleotides upstream of the poly(A) site (Chen, MacDonald, & Wilusz, 1995) and (2) the downstream element ...
EctB is a 421-residue protein with a molecular mass of 46.1 kDa, which requires K 1 for its transaminase activity and for protein stability. Gel filtration experiments with purified protein from H. elongata indicate that the DABA aminotransferase ectB might form a homohexamer in the native state...
A molecule composed of a small number of linked monomer units; a short polymer; - compounds called oligomers have less than one hundred monomer units and usually less than thirty. Oligomers of increasing length are called dimer, trimer, tetramer, pentamer, hexamer, heptamer, octamer, nonamer, ...

Tenascin C TNC is an ECM protein that assembles into a hexamer via a disulfide bond at the N terminus. TNC comprises several functional structural domains, including a C-terminal globular structural domain, a heptapeptide repeat sequence, an epidermal growth factor-like repeat sequence, and a ...
The analysis also found that, in addition to KaiA, KaiB and KaiC, the test tube also contained large amounts of the three smaller molecules, called monomers, that are the basic building blocks for the bioclock proteins. KaiC is a hexamer that is made up of six monomers. KaiA is a dimer...
The tsetse fly (Glossina genus) is the main vector of African trypanosomes, which are protozoan parasites that cause human and animal African trypanosomiases in Sub-Saharan Africa. In the frame of the IAEA/FAO program ‘Enhancing Vector Refractoriness to
What is Sodium Hexametaphosphate? Sodium hexametaphosphate is an inorganic salt having the chemical formula Na6[(PO3)6]. Commercially, it typically occurs as a mixture of metaphosphates having a hexamer form. More precisely, this type of mixture can be named asodium polymetaphosphate. This...
