Specification

• Description: CpG methylation is an epigenetic modification that is important for embryonic development, imprinting, and X-chromosome inactivation. Studies in mice have demonstrated that DNA methylation is required for mammalian development. This gene encodes a DNA methyltransferase which is thought to function in de novo methylation, rather than maintenance methylation. The protein localizes primarily to the nucleus and its expression is developmentally regulated. Mutations in this gene cause the immunodeficiency-centromeric instability-facial anomalies (ICF) syndrome. Eight alternatively spliced transcript variants have been described. The full length sequences of variants 4 and 5 have not been determined.

Q&As

What are the potential side effects of targeting DNMT3B for therapeutic purposes?

Targeting DNMT3B for therapeutic purposes may lead to off-target effects and unintended changes in DNA methylation, potentially causing adverse effects on normal cellular function and gene expression.

Are there any genetic disorders associated with mutations in the DNMT3B gene?

Yes, mutations in the DNMT3B gene are linked to a rare genetic disorder called ICF (Immunodeficiency, Centromeric instability, Facial anomalies) syndrome, characterized by immune system deficiencies, facial abnormalities, and unstable centromeric regions in chromosomes.

Can DNMT3B protein be used as a potential biomarker for cancer diagnosis or prognosis?

Research has shown that alterations in DNMT3B expression or activity can be associated with various types of cancer, making it a potential biomarker for cancer diagnosis, prognosis, and treatment response.

How does DNMT3B protein contribute to epigenetic regulation in cells?

DNMT3B plays a crucial role in establishing de novo DNA methylation patterns during embryonic development and cell differentiation, contributing to the epigenetic regulation of gene expression.

What are the therapeutic implications of targeting DNMT3B in cancer treatment?

Inhibition of DNMT3B activity through targeted therapy or epigenetic modifying agents has been explored as a potential treatment strategy to reverse abnormal DNA methylation patterns and restore normal gene expression in cancer cells.
