Figure 5B shows that only 45 aa staple was able to confer the SDS resistance to the stapling system, confirming possible utility of the longer linker in aiding visualization of stapled products in SDS-PAGE gels.
In vertebrate the presence of the longer linker region in TERT proteins of different species correlates with evolutionary distribution of interstitial telomeric sequences (ITS).
DOI: http://dx.doi.org/10.7554/eLife.03772.014 If the IGF1R ECD inhibits IGF1R activity by enforcing TM separation, introduction of flexible linkers between the ECD and TM regions should release this inhibition, and insertion of progressively longer linkers composed of glycine serine containing repeats between 4 and 20 residues long indeed led to increasing levels of basal receptor activity.
We further cloned deletion constructs of N-terminal domain (NTD) consisting of 1 to 121 residues and N-terminal domain with longer linker consisting of 1 to 144 residues (NTDL).
Recent data further show that mutating the SLIDE domain within the ISW2 complex reduces the ability of the complex to move the longer linker DNA into the nucleosome (Hota et al., 2013).
In the case of yT1, nearly half the G0 parents produced mutant offspring, and 20% of all F1s were mutant, an increase of more than 30-fold over the longer linker.
Most current approaches to linker selection and design processes for fusion proteins are still largely dependent on experience and intuition; such selection processes often involve great uncertainty, particularly in the case of longer flexible linker selection, and many unintended consequences, such as the misfolding, low yield and reduced functional activity of fusion proteins may occur.
It differs from Hyper-CNTF, since the additional glycine residue was not incorporated in the fusion and also the flexible termini of sIL-11Rα and IL-11 generated a longer linker.
In general, the FRET efficiency between the Cherry-cpV constructs is higher than that of the mCherry-SYFP2 construct, probably due to the longer linker in the latter construct.
Longer linker size seems to be a general feature of tCWCH2, but conservation of the linker sequences within each class varies notably.
