Tab2 was first identified in Chlamydomonas reinhardtii as a RNA binding protein required for translation of the chloroplast PsaB photosystem I subunit [ 1 , 2 ]. Later, the Tab2 homologue from Arabidopsis was found involved in the signalling pathway of light-controlled synthesis of photosystem proteins during early plant development [ 3 ]. Proteins in this entry are from photosynthetic organisms including plants and cyanobacteria.
