| Primary Identifier | IPR046761 | Type | Domain |
| Short Name | Tab2-like_C |
| description | This entry represents the C-terminal domain of Tab2 from plants and cyanobacteria. Tab2 was first identified in Chlamydomonas reinhardtii ([swissprot]:Q7X8Y6) as a RNA-binding protein required for translation of the chloroplast PsaB photosystem I subunit []. Later, the Tab2 homologue from Arabidopsis (ATAB2) was found involved in the signalling pathway of light-controlled synthesis of photosystem proteins during early plant development, presumably functioning as an activator of translation with targets at PSI and PSII [, ]. Directed mutagenesis experiments carried out in Tab2 from C.reinhardtii indicated the importance of a highly conserved C-terminal tripeptide WLL for normal psaB translation []. |
