Figure 2. Subcellular localization of Sar1 in rice protoplasts.[1].
Function
- Sar1, a small GTPase, acts as a molecular switch to regulate the assembly of coat protein complex II, which exports secretory protein from the ER to the Golgi apparatus.
- There are four putative Sar1 genes (OsSar1a, OsSar1b, OsSar1c, OsSar1d) in rice.
- OsSar1a/b/c play a crucial role in storage proteins exiting from the ER, with functional redundancy in rice endosperm, and glutelin and α-globulin transported together from the ER to the Golgi apparatus by a pathway mediated by coat protein complex II.
Subcellular localization
- OsSar1 was fused with mCherry (OsSar1–mCherry) and co-expressed with yellow fluorescent protein (YFP)–AtSec24, which labels ERES 2009), in rice protoplast cells. The punctate structures labelled with OsSar1–mCherry coincided with YFP–AtSec24 fluorescence (Fig. 2B), and the distribution pattern of the four Sar1 proteins was similar.
- These data indicated that the OsSar1 isoforms were distributed at ERES, at the ER, and in the cytosol.
