Here, we show that multimers constructed from peptide-human leukocyte antigen (pHLA) A⁎0201 monomers engineered in the heavy chain α2 domain to enhance CD8 binding (KD ≈ 85 μM) without impacting the TCR binding platform can detect cognate CD8+ T cells bearing low affinity TCRs that are not visible with the corresponding wildtype pHLA A⁎0201 multimeric complexes.
Formally, this hypothesis states that one modification or specific combinations of histone modifications can affect distinct downstream events by altering the structure of the chromatin and/or generating a binding platform for protein effectors that can specifically recognise the modification(s) and initiate gene transcription or repression.
The player can jump and run on platforms, and can jump off or slide down walls.
DROMPA outputs protein-binding profiles and identifies peaks as bar graphs in a pdf or png format, both of which are compatible with many computer platforms and can be handled without installation of an additional visualization program.
Manipulation of the fluorophore and binding motif platform can tune the efficiency of PET, affecting the brightness in both the bound and the unbound states of the sensor and therefore the magnitude of fluorescence change with Zn2+ binding.
The external hemagglutinin (HA) glycoprotein mediates receptor binding, fusion, and can generate both strong antibody and cell-mediated immune responses [16] which can be directly assayed and provide useful comparison of adenovirus platforms.
This binding mode explains the large number of EB binding sites at growing microtubule ends (Maurer et al., 2011) and emphasizes that the microtubule-end region can serve as a binding platform for many hundreds of +TIP molecules.
For example, methylation of specific lysine residues in a defined state (mono-, di-, or trimethyl) can serve as a binding platform for effector proteins containing one of the following types of methyl-binding domains: chromodomain, tudor domain, PHD finger, MBT, Ankyrin repeat, PWWP domain and WD40 repeats [12], [13], [14].
It can either constitute a binding platform for the regulators of transcriptional machinery or temporarily interfere with the binding or activity of factors targeted to adjacent residues.
EJC provides a binding platform for factors involved in mRNA splicing, export and non-sense mediated decay (NMD).
