Mass Spectrometry analysis of a Arabidopsis protein


ABSTRACT: We identified a Arabidopsis protein BSF, and it has a role in the stabilization and translation of chloroplast mRNAs. To further study it's function, we purified BSF-associated proteins for mass spectrometry analysis.

A key characteristic of chloroplast gene expression is the predominance of posttranscriptional control via numerous nucleus-encoded RNA binding factors. Here, we explored the essential roles of the S1-domain-containing protein <i>photosynthetic electron transfer B</i> (<i>petB</i>)/ <i>petD</i> Stabilizing Factor (BSF) in the stabilization and translation of chloroplast mRNAs. BSF binds to the intergenic region of <i>petB</i>-<i>petD</i>, thereby stabilizing 3' processed <i>petB</i> transcripts  ...[more]
