Article CAS Google Scholar WebSep 15, 1999 · The CACNA1G CpG island is 4 kb and is larger than many typical CpG islands. MINT31 corresponds to the 5′ edge of the island, whereas CACNA1G is in the 3′ region. It is not known whether large CpG islands such as this are coordinately regulated with regards to protection from methylation and aberrant methylation in cancer.
