MBT Domain Screening


Motivating the research toward targeting malignant brain tumor (MBT) domains is their role in oncogenesis. The MBT domain, named after the l (3) mbt family of tumor suppressor genes, is a motif of approximately 100 amino acids found in tandem repeats in proteins that bind to the lower methylation states of lysine residues present in histone tail peptides. MBT domains are known to localize to chromatin and repress transcription. They are unique within the methyllysine reader family because of their highly predictable druggability and domain-repeat structures.

Creative BioMart utilizes the affinity of AlphaScreen beads to detect the binding of various histone tail peptides with lower methylation states to MBT proteins for the discovery of MBT domain antagonists.

MBT Domain Screening Assay at Creative BioMart

The HTS assay based on amplified luminescence proximity homogeneous assay (AlphaScreen) technology is ideal for use as a screening assay in the discovery of inhibitors of binding partners that interact with Kd values in the micromolar range.

When excited at 680 nm, the donor beads convert ambient oxygen to singlet oxygen. If the beads are within 200 nm of each other, then the singlet oxygen initiates a chemiluminescent reaction in the acceptor bead that emits light in the range of 520-620 nm. The donor beads can produce thousands of singlet oxygen molecules per second, resulting in the amplification of the binding signal.
