General annotation (Comments)

Function

Required for the splicing of group IIB introns in chloroplasts. Forms splicing particles with CRS2. Interacts with RNA and confers intron specificity of the splicing particles. Ref.1

Subunit structure

Interacts with CRS2 and RNA. Part of large ribonucleo-protein complexes that include group IIB introns, CRS2 and CAF1. Ref.1 Ref.2

Subcellular location

Plastidchloroplast stroma Ref.1.

Sequence similarities

Contains 2 CRM domains.
