Summary: This is one of two related genes encoding de novo DNA methyltransferases, which are responsible for the establishment of DNA methylation patterns in embryos. Loss of function of this gene causes developmental defects in multiple different organ systems. There is a pseudogene for this gene located on chromosome 3. Alternatively spliced transcript variants encoding multiple isoforms have been observed. [provided by RefSeq, Nov 2012]
Expression: Ubiquitous expression in limb E14.5 (RPKM 12.7), CNS E11.5 (RPKM 11.1) and 28 other tissues See more

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Description

Transcript Variant: This variant (2) represents use of an alternate promoter, compared to variant 1. It differs in the 5' UTR, lacks a portion of the 5' coding region, and initiates translation at a downstream in-frame start codon. The encoded isoform (2, also known as Dnmt3a2) has a shorter N-terminus, compared to isoform 1.
