May act as the scaffold of a protein complex, which sequesters key factors that are required for the G2 to M transition in meristematic tissues (By similarity). Together with REC2, REC3 and FMT/CLU, contributes to the establishment of the cellular volume devoted to the chloroplast compartment (PubMed:26862170). Reduced proportion of the cellular volume devoted to chloroplasts leading to an abnormal chloroplasts distributions (PubMed:26862170). Lower levels of chlorophyll, especially in plants lacking REC1, REC2, REC3 and FMT/CLU (PubMed:26862170).
