The strict regulation of translation in both space and time is in part governed by cis-regulatory elements located in 5′ mRNA transcript leaders (TLs) and 3′ untranslated regions (UTRs). Due to their role in translation initiation, mRNA 5′ transcript leaders (TLs) strongly influence protein expression.
Cis AB is a type of rare mutation in the ABO gene. It happens when the transferase allele contains a mix of amino acids from either A or B alleles, producing a bifunctional enzyme that can produce both types of antigens, usually with one weaker than the other. This results in a serum test result much like the standard, separate (trans) AB ...
In biochemistry, cis-trans isomerase is a type of isomerase which catalyzes the isomerization of geometric isomers. Examples include retinal isomerase and immunophilins such as cyclophilin . External links
Figure 1: Orientations of cis-NATs within the genome. Cis-NATs have a variety of orientations and differing lengths of overlap between pairs. [7] There have been five identified orientations for cis-NATs to date. [8] The most common orientation is head-to-head, where the 5' ends of both transcripts align together. [3]
This is a list of cis-regulatory RNAs. These are RNA motifs which regulate nucleic acid regions on the same molecule, as opposed to trans -acting motifs which regulate a distal molecule. Some of these RNAs are broadly distributed while others are single RNA families.
The activation energy required to catalyse the isomerisation between cis and trans is relatively high: ~20kcal/mol (cf. ~0kcal/mol for regular peptide bonds). Unlike regular peptide bonds, the X-prolyl peptide bond will not adopt the intended conformation spontaneously, thus, the process of cis-trans isomerization can be the rate-limiting step ...
An expression quantitative trait is an amount of an mRNA transcript or a protein.These are usually the product of a single gene with a specific chromosomal location. This distinguishes expression quantitative traits from most complex traits, which are not the product of the expression of a single gene.
The Kurnakov test, also known as Kurnakov's reaction, is a chemical test that distinguishes pairs of cis- and trans-isomers of [PtA 2 X 2] (A = NH 3, X = halogen or pseudohalide). Upon treatment with thiourea , the trans -dihalides give less soluble white products, whereas the cis -dihalides give more soluble yellow products.
