Summary: Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity; chromatin binding activity; and histone H3K9me2 methyltransferase activity. Involved in circadian rhythm; male meiotic nuclear division; and negative regulation of macromolecule biosynthetic process. Located in heterochromatin and nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system; and limb. Orthologous to human SUV39H2 (SUV39H2 histone lysine methyltransferase).

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) lacks an alternate exon compared to variant 1. The resulting transcript is a candidate for nonsense-mediated mRNA decay (NMD) and therefore is not thought to encode a protein.
