ATP4 — Brassica juncea

Summary

BJUA01G26160S (ATP4) on chromosome A01 of Indian mustard (Brassica juncea) encodes a protein containing Smr, PROP1-like PPR, and PPR repeat domains, along with a TPR-like helical domain superfamily. The product binds pre-rRNA, single-stranded RNA, identical proteins, and mRNA. It is associated with chloroplast RNA processing, group II intron splicing, positive regulation of translation, mRNA stabilization, mRNA processing, and regulation of translation. The protein localizes to the chloroplast stroma, mitochondria, and cytoplasm. This gene has been connected to cytoplasmic male sterility. Studies of related genes in other species link the family to similar RNA processing and fertility restoration functions.
