Abstract
- Small ubiquitin-related modifier (SUMO) genes regulate various functions of target proteins through post-translational modification. The SUMO proteins have a similar 3-dimensional structure as that of ubiquitin proteins and occur through a cascade of enzymatic reactions. In the present study we have cloned a new SUMO gene from Tomato (Solanum lycopersicum L.), cv Saudi-1, named SlS-SUMO1 gene by PCR using specific primers. This gene has SUMO member's features such as C-terminal diglycine (GG) motif as processing site by ULP (ubiquitin-like SUMO protease) and has SUMO consensus ΨKXE/D sequence. Phylogenetic analysis showed that SlS-SUMO1 gene is highly conserved and homologous to Potatoes Ca-SUMO1 and Ca-SUMO2 genes based on sequence similarity. Expression protein of SlS-SUMO1 gene found to be localized in the nucleus, cytoplasm, and nuclear envelop or nuclear pore complex. SUMO conjugating enzyme SCE1a with SlS-SUMO1 protein co-expressed and co-localized in nucleus and formed nuclear subdomains. This study reported that the SlS-SUMO1 gene is a member of SUMO family and its SUMO protein processing using GG motif and activate and transport to nucleus through Sumoylation system in the plant cell.
