We utilize highly promiscuous biotinylation enzymes to capture transient or low-affinity co-repressors, overcoming the major limitation of conventional pull-down methods and uncovering genuinely novel research targets.
MBD/MeCP2 mediated Repression Complex Mapping Service
Creative Biolabs constitutes a definitive methodological approach for the resolution of complexity inherent in methylation-mediated gene silencing mechanisms. We deliver an unparalleled, unbiased identification of the entire protein complex recruited by Methyl-CpG-Binding Domain (MBD) proteins, such as MeCP2. Consequently, clients are positioned to obtain novel, high-confidence protein targets and the requisite mechanistic data necessary for distinguishing between normal and pathologically altered regulatory states, thereby significantly accelerating the initial phases of specific research compound development.

Introduction of MBD/MeCP2-Mediated Repression Complex Mapping Service
DNA methylation at CpG dinucleotides is a fundamental mechanism of transcriptional silencing, primarily mediated by MBD proteins, such as MeCP2. This methodology addresses the challenge presented by the methylation mark's complexity, which arises from up to fifteen chemical combinations due to TET enzyme activity. The service yields an unbiased, high-resolution inventory of the corepressor complexes recruited by these MBD proteins, thereby advancing epigenetic profiling toward definitive mechanistic discovery.

Customer Reviews

MeCP2 Mutant Validation
The high-resolution mapping facilitated our MeCP2 mutant study by providing molecular evidence of altered interaction profiles. This was crucial for our grant application, as the data directly supported the hypothesis that RTT mechanisms stem from a shift in MeCP2's ability to "read" the diverse modified CpG landscape, moving beyond simple loss-of-function models. - Dr. A. P. Ja***nes -
Locus-Specific Specificity
We used this service to map the MBD1 complex at two different promoter sites. The results clearly showed that the recruited complex components were locus-specific, confirming the power of the in situ proximity labeling approach to differentiate complex composition at the single-gene level. This is a clear advantage over bulk protein interaction studies. - Prof. B. M. Da***son.
FAQs
Can this service differentiate between wild-type and research-associated MeCP2 mutants?
Yes. Research shows that MeCP2 mutants exhibit altered binding profiles for specific modified CpG combinations. Our PL-MS approach is sensitive enough to detect how these mutations change the pattern of recruited co-repressors, providing molecular targets for research to selectively inhibit the altered function of the mutant protein.
What type of samples can Creative Biolabs accept for this mapping service?
We accept a wide range of samples, including primary cell cultures and established cell lines (with stable or inducible tagging options). We can optimize for low cell counts typical of complex biological models. The main requirement is high-quality input DNA and/or a viable cell model for genetic tagging.
