A new DEAD-box helicase ATP-binding protein (OsABP) from rice is responsive to abiotic stress.
The DEAD-box RNA helicase family comprise enzymes that participate in every aspect of RNA metabolism, associated with a diverse range of cellular functions including response to abiotic stress. In the present study, we report on the identification of a new DEAD-box helicase ATP-binding protein (OsABP) from rice which is upregulated in response e to multiple abiotic stress treatments  including NaCl, dehydration, ABA, blue and red light. It possesses an ORF of 2772 nt, encoding a protein of 923 aa, which contains the DEAD and helicase C-terminal domains, along with the nine conserved motifs specific to DEAD-box helicases. The in silico putative interaction with other proteins showed that OsABP interacts with proteins involved in RNA metabolism, signal transduction or stress response. These results imply that OsABP might perform important functions in the cellular response to specific abiotic stress.
