NCBI Protein Information
SU(VAR)3-9 homolog 9
NCBI Summary
Encodes a SU(VAR)3-9 homolog, a SET domain protein. Known SET domain proteins are involved in epigenetic control of gene expression and act as histone methyltransferases. There are 10 SUVH genes in Arabidopsis and members of this subfamily of the SET proteins have an additional conserved SRA domain. A plant line expressing an RNAi construct directed against this gene has reduced agrobacterium-mediated tumor formation.

UniProt Comments
Histone methyltransferase family member that plays a role in gene silencing (PubMed:19043555, PubMed:24463519, PubMed:27171427). Together with MORC6 and SUVH2, regulates the silencing of some transposable elements (TEs) (PubMed:27171427). According to PubMed:19043555, the protein does not bind S-adenosyl-L-methionine and lacks methyltransferase activity. Instead, it may function downstream of DRM2 in RNA-directed DNA methylation, binding to methylated DNA and recruiting DNA-directed RNA polymerase V to chromatin (PubMed:24463519, PubMed:27171427).
