PPR-SMRs: ancient proteins with enigmatic functions.

RNA biology - 1 Jan 2013

Liu Sheng, Melonek Joanna, Boykin Laura M, Small Ian, Howell Katharine A

Abstract excerpt

A small subset of the large pentatricopeptide repeat (PPR) protein family in higher plants contain a C-terminal small MutS-related (SMR) domain. Although few in number, they figure prominently in the chloroplast biogenesis and retrograde signaling literature due to their striking mutant phenotypes. In this review, we summarize current knowledge of PPR-SMR proteins focusing on Arabidopsis and maize proteomic and...
