Collaboratively with CYP40/SQN and ULT1, influences floral meristem (FM) determinacy in an AGAMOUS and SUPERMAN-dependent manner, thus contributing to the floral developmental homeostasis. Interacts with SWA2, NOC2 and NOC3 in both the nucleolus and nucleoplasm (PubMed:30338215). Binds to ENAP1 and OBE1 (PubMed:30338215). Observed in the nucleolus of root cells in interphase and colocalizes with DNA in dividing root cells. Expressed at low levels in roots, shoots, leaves, stems, inflorescences, flowers and siliques, with highest levels dividing tissues. Plants lacking both CRC and RBL exhibit strong floral meristem (FM) indeterminacy with reiterations of extra floral whorls in the center of the flower associated with reduced AGAMOUS and SUPERMAN levels. 'Rebelote' means once again in French. Belongs to the NOC2 family.
