Protein: DExH-box ATP-dependent RNA helicase DExH15 chloroplastic (EC 3.6.4.13) (ATP-dependent RNA helicase ISE2) (Protein EMBRYO DEFECTIVE 25) (Protein INCREASED SIZE EXCLUSION LIMIT 2) (Protein PIGMENT DEFECTIVE 317) (B9DFG3)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: RNA helicase involved in group II intron splicing. Essential protein required during embryogenesis. Involved in post-transcriptional gene silencing. Modulates the determination of cell fate. Necessary for normal plasmodesmata (PD) development and aperture regulation.
Subcellular location: Plastid, chloroplast {ECO:0000269|PubMed:18431481, ECO:0000269|PubMed:22106293, ECO:0000269|PubMed:26147377}. Cytoplasmic granule {ECO:0000269|PubMed:17601829}. Note=Localizes to granule-like structures, probably stress granules (SGs), which number increases upon stress. {ECO:0000269|PubMed:17601829}.
