sir-2.2 encodes one of four C. elegans proteins with similarity to the Saccharomyces cerevisiae Sir2p NAD-dependent histone deacetylase; SIR-2.2 may play a role in genomic stability and protecting the genome against mutations, as loss of SIR-2.2 function via RNA-mediated interference (RNAi) results in an increased level of spontaneous mutagenesis.
Predicted to enable NAD+ binding activity and NAD-dependent histone deacetylase activity. Involved in innate immune response. Located in mitochondrion. Is an ortholog of human SIRT4 (sirtuin 4).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
