Recombinant full-length human Bcl-xL was cloned into PTYB1 vector to produce a fusion of Bcl-xL with an intein/chitin binding protein, which can be removed to obtain Bcl-xL with vector encoded residues Gly Ser Ser at the C terminus.
Classically, the cytotoxic compound is conjugated to the targeting mAb via nondirected chemical linkage, often resulting in an undefined stoichiometry of ADCs and heterogenic positioning of the cytotoxic payload in relation to the binding protein, which can directly affect its therapeutic efficacy (Ducry and Stump, 2010).
The marine mussel, Mytilus edulis, possesses low molecular weight, metal-binding proteins which can be induced by and, in turn, bind mercury when individuals are exposed to low, but elevated concentrations of mercury as HgCl2.
With advancements in using such editing tools as zinc finger nucleases (ZFNs), meganucleases, and transcription activator-like effector nucleases (TALENs), etc., scientists are able to design DNA-binding proteins, which can make precise double-strand breaks (DSBs) at the target DNA.
Four different repeat domains can be mixed and matched to create new DNA-binding proteins, which can be linked to the FokI domain to create a new class of programmable target DNA nucleases (Miller et al., 2011).
Drosha and Dicer act as components of larger complexes containing accessory proteins, often double-stranded RNA-binding proteins, which can activate or repress the activity of these complexes.
A further relation to muscle function can be found in the histidine-rich Ca2+-binding protein which can also bind Zn and is localized in the sarcoplasmic reticulum [ 135].
