Protein
Chloroplastic group IIB intron splicing facilitator CRS2, chloroplastic
Function
Required for the splicing of group IIB introns in chloroplasts. Forms complexes with either CAF1 or CAF2 which, in turn, interact with RNA and confer intron specificity of the splicing particles. Has no peptidyl-tRNA hydrolase activity.
Similarity
Belongs to the PTH family. CRS2 subfamily.
