UniProtKB - Q9LYA9 (CP41A_ARATH)
Chloroplast stem-loop binding protein of 41 kDa a, chloroplastic
CSP41A
Functioni
Binds and cleaves RNA, particularly in stem-loops. Associates with pre-ribosomal particles in chloroplasts, and participates in chloroplast ribosomal RNA metabolism, probably during the final steps of 23S rRNA maturation. May enhance transcription by the plastid-encoded polymerase and translation in plastid via the stabilization of ribosome assembly intermediates. Required for chloroplast integrity. Involved in the regulation of the circadian system.
