    Also known as
    chloroplast RNA binding; CHLOROPLAST RNA BINDING; CHLOROPLAST STEM-LOOP BINDING PROTEIN OF 41 KDA; CHLOROPLAST STEM-LOOP BINDING PROTEIN OF 41 KDA; CRUCIFERIN B; CSP41B; heteroglycan-interacting protein 1.3; HIP1.3
    Summary
    Encodes CHLOROPLAST RNA BINDING (CRB), a putative RNA-binding protein. CRB is important for the proper functioning of the chloroplast. Mutations in CRB also affects the circadian system, altering the expression of both oscillator and output genes.
