ATP4 — Brassica juncea

Summary

BJUA08G10660S (ATP4) in Indian mustard (Brassica juncea) on chromosome A08 encodes a protein containing Smr, PROP1-like PPR, and PPR repeat domains, with molecular functions including pre-rRNA binding, single-stranded RNA binding, mRNA binding, and identical protein binding. It is associated with chloroplast RNA processing, group II intron splicing, positive regulation of translation, mRNA stabilization, and mRNA processing, and localizes to the chloroplast stroma, mitochondria, and cytoplasm. The gene is linked to cytoplasmic male sterility. Studies of related genes in other species connect the family to similar RNA processing roles in organelles.
