Description

General description

SIRT5 is a member of the sirtuin family of proteins which are homologs to the yeast Sir2 protein. Sirtuin family contain a sirtuin core domain and are grouped into four classes with SIRT5 being a member of class III. SIRT5 consists of eight exons and is found in two isoforms which encode a 310 aa and a 299 aa protein, respectively. Human SIRT5 is most predominantly expressed in heart muscle cells and in lymphoblasts. Fluorescence in situ hybridization analysis localized the human SIRT5 gene to chromosome 6p23. SIRT5 can deacetylate cytochrome c, a protein of the mitochondrial intermembrane space with a central function in oxidative metabolism as well as apoptosis initiation.

Biochem/physiol Actions

Sirtuins are NAD⁺-dependent deacetylases. Sirtuin 5 (SIRT5) catalyzes the degradation of negatively charged acylated substrates. It also possesses desuccinylase, demalonylase and deglutarylase activities. The protein is overexpressed in non-small cell lung cancer (NSCLC) and may have a role in cancer growth.
