positive regulation of gene expression via chromosomal CpG island demethylation

Term ID

GO:0044029

Synonyms

• DNA demethylation
• DNA hypomethylation of CpG island
• hypomethylation of CpG island
• positive regulation of gene expression via chromosomal CpG dinucleotide demethylation

Definition

An epigenetic gene regulation mechanism that positively regulates gene expression by demethylation of cytosine residues in chromosomal CpG islands. CpG islands are genomic regions that contain a high frequency of the CG dinucleotide and are often associated with the transcription start site of genes. (2)
