- DNA (cytosine 5) methyltransferase 3 alpha
- DNA (cytosine 5) methyltransferase 3A
- DNA (cytosine-5)-methyltransferase 3A
FunctionRequired for genome wide de novo methylation and is essential for the establishment of DNA methylation patterns during development. DNA methylation is coordinated with methylation of histones. It modifies DNA in a non-processive manner and also methylates non-CpG sites. May preferentially methylate DNA linker between 2 nucleosomal cores and is inhibited by histone H1. Plays a role in paternal and maternal imprinting. Required for methylation of most imprinted loci in germ cells. Acts as a transcriptional corepressor for ZNF238. Can actively repress transcription through the recruitment of HDAC activity.
Tissue specificityHighly expressed in fetal tissues, skeletal muscle, heart, peripheral blood mononuclear cells, kidney, and at lower levels in placenta, brain, liver, colon, spleen, small intestine and lung.
Sequence similaritiesBelongs to the C5-methyltransferase family.
Contains 1 ADD domain.
Contains 1 GATA-type zinc finger.
Contains 1 PHD-type zinc finger.
Contains 1 PWWP domain.
DomainThe PWWP domain is essential for targeting to pericentric heterochromatin.
modificationsSumoylated; sumoylation disrupts the ability to interact with histone deacetylases (HDAC1 and HDAC2) and repress transcription.
Cellular localizationNucleus. Cytoplasm. Accumulates in the major satellite repeats at pericentric heterochromatin.
