The phrase "a molecular tether" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in discussions about molecular biology, chemistry, or biochemistry, where it refers to a structure that connects or links molecules together.
Example: "The researchers designed a molecular tether to facilitate the interaction between the two proteins in the experiment."
Alternatives: "a molecular link" or "a molecular connector".
These data underline the close coupling of processes in the initial stages of protein-encoding gene expression and provide evidence for a molecular tether connecting emergent splice sites in the pre-mRNA to transcribing RNA Pol II.
With a molecular tether in between six uncharged sugars, the synthetic compound is only 17 sugars long, compared to heparin's hundreds.
More recently, Kornmann et al. (2009) identified a complex, the ER mitochondria encounter structure (ERMES), that acts as a molecular tether between ER and mitochondria in Saccharomyces cerevisiae and is required for efficient inter-organelle phospholipid exchange.
The size and nature of the interface in the complex indicates that the CTD is a specific molecular tether for the constitutive engagement of the B subunit with the polymerase subunit.
In the midst of this complex system, perhaps at multiple sites, lies the exocyst, a putative molecular tether that facilitates secretory vesicle delivery for fusion to the plasma membrane in both plant [ 19, 34, 35] and non-plant species [ 16- 18, 23].
Pd(pyca)(PPh3)(OTs) [pyca = 2-picolinate] complex is efficiently anchored inside different mesoporous matrices, such as MCM-41, MCM-48, SBA-15 using a molecular aminopropyl tether moiety employing different synthesis strategies.
In meiotic prophase, Mps3 relocalizes from the SPB to telomere attachment sites at the NE consistent with establishment the molecular tether (Conrad et al. 2007).
We propose a model for cell-regulated collagen fibril assembly during tendon development in which MMP14 cleaves a molecular bridge tethering collagen fibrils to the plasma membrane of fibripositors.
Molecular tethers have a central role in the organization of the complex membrane architecture of eukaryotic cells.
In more compact states, energy (mechanical stress) is stored within the chromosomes because the chromatin fiber is spatially constrained by molecular tethers.
Also, chromosomes are held in this compact prophase state by two types of molecular tethers – cohesin and Topoisomerase II-sensitive linkages (probably catenations).
