ATP4 — Brassica juncea

Summary

BJUB04G25630S, also known as ATP4, BjMS77, or NFD5 in Indian mustard (Brassica juncea) on chromosome B04, encodes a protein containing CCM1-like_TPR, PROP1-like_PPR_dom, PPR_rpt, and TPR-like_helical_dom_sf domains. The gene product binds pre-rRNA, single-stranded RNA, mRNA, and identical proteins, and is associated with chloroplast stroma and cytoplasm localisation. It is associated with karyogamy, polar nucleus fusion, chloroplast RNA processing, group II intron splicing, positive regulation of translation, mRNA stabilization, and mRNA processing. This gene is associated with cytoplasmic male sterility. Related genes in other species link the family to defective polar nuclei fusion in the female gametophyte and to protein content.
