Protein Name:
Ribonuclease TUDOR 1
|
UniprotKB/SwissProt ID: Q8VZG7 (Q8VZG7)
Gene Name:
TSN1
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Cytoprotective ribonuclease (RNase) required for resistance to abiotic stresses, acting as a positive regulator of mRNA decapping during stress (PubMed:25736060). Essential for the integrity and function of cytoplasmic messenger ribonucleoprotein (mRNP) complexes called stress granules (SGs) and processing bodies (PBs), sites of post-transcriptional gene regulation during stress (e.g. salt and heat) (PubMed:25736060). Involved in gibberellic acid (GA) biosynthesis (PubMed:25205572). Essential for stress tolerance, probably by regulating mRNAs entering the secretory pathway (PubMed:20484005). Component of stress granules (SGs) that regulates growth under salt stress by modulating levels of GA20OX3 mRNA. Binds GA20OX3 mRNA (PubMed:25205572). May inhibit the degradation of mRNAs involved in stress adaptation (PubMed:26237081)
