Genbank accession number
- Key message
- OsBAT1 transcript levels are enhanced in rice seedlings in response to abiotic stress including salt stress and abscisic acid
- This study demonstrates several unique characteristics of OsBAT1 especially its ability to unwind both DNA and RNA duplexes; bipolar translocation and its transcript upregulation under abiotic stresses indicate that it is a multifunctional protein
- Overall, this study represents significant contribution in advancing our knowledge regarding functions of OsBAT1 in RNA and DNA metabolism and its putative role in abiotic stress signaling in plants
- Interestingly OsBAT1 also exhibits unique DNA helicase activity, which has not been reported so far in any BAT1 homologue
- The K m value for OsBAT1 DNA helicase is 0
- Connection
- OsAIP1~OsBAT1, OsAPI5, Rice APOPTOSIS INHIBITOR5 coupled with two DEAD-box adenosine 5’-triphosphate-dependent RNA helicases regulates tapetum degeneration, Os API5 is a nuclear protein that interacts with two DEAD-box ATP-dependent RNA helicases, API5-INTERACTING PROTEIN1 (AIP1) and AIP2
- OsAIP1~OsBAT1, OsCP1, Rice APOPTOSIS INHIBITOR5 coupled with two DEAD-box adenosine 5’-triphosphate-dependent RNA helicases regulates tapetum degeneration, Os AIP1 and AIP2 can form dimers and interact directly with the promoter region of CP1, a rice cysteine protease gene
- OsAIP1~OsBAT1, OsCP1, Rice APOPTOSIS INHIBITOR5 coupled with two DEAD-box adenosine 5’-triphosphate-dependent RNA helicases regulates tapetum degeneration, Suppression of Os AIP1/2 leads to down-regulation of CP1, resulting in sterility, which is highly similar to the effects of suppressed expression of Os CP1
- OsAIP1~OsBAT1, OsAIP2, Rice APOPTOSIS INHIBITOR5 coupled with two DEAD-box adenosine 5’-triphosphate-dependent RNA helicases regulates tapetum degeneration, Os API5 is a nuclear protein that interacts with two DEAD-box ATP-dependent RNA helicases, API5-INTERACTING PROTEIN1 (AIP1) and AIP2
- OsAIP1~OsBAT1, OsAIP2, Rice APOPTOSIS INHIBITOR5 coupled with two DEAD-box adenosine 5’-triphosphate-dependent RNA helicases regulates tapetum degeneration, AIP1 and AIP2 are homologs of yeast (Saccharomyces cerevisiae) Suppressor of Bad Response to Refrigeration1 protein 2 (SUB2p) that have critical roles in transcription elongation and pre-mRNA splicing
- OsAIP1~OsBAT1, OsAIP2, Rice APOPTOSIS INHIBITOR5 coupled with two DEAD-box adenosine 5’-triphosphate-dependent RNA helicases regulates tapetum degeneration, Os AIP1 and AIP2 can form dimers and interact directly with the promoter region of CP1, a rice cysteine protease gene
