RNA binding protein with nuclease activity essential for stress response. Involved in mechanisms acting on mRNAs entering the secretory pathway. Functionally redundant with TSN2.
Tight regulation of the AtRBP1 transcript may be required for normal root growth...In vivo selection of RNAs bound to AtRBP1 suggests that transcripts of At3g06780, At4g15910, At5g11760 and At5g07350 are target RNAs of AtRBP1.
