CRB — Cucumis melo

Summary

MELO3C012888.2 (symbol CRB, also known as CmCRB) on melon chromosome 5 encodes a seed storage protein belonging to the 11S globulin family, characterized by cupin domains and nutrient reservoir activity. The gene product is associated with IgG and IgE binding, protein phosphorylated amino acid binding, and ATP binding. It has been linked to numerous biological processes including fruit development and ripening, seed development and germination, flower development, sex determination, carpel and stamen development, abscission, photoprotection, xanthophyll metabolism, abscisic acid and ethylene anabolism, brassinosteroid-mediated signalling, and regulation of superoxide release. Localization evidence connects the protein to the endosperm protein body, vacuole, chloroplast envelope and stroma, LHCII, plasmodesmata, mitochondria, and extraorganismal space. Associations with traits include violaxanthin and neoxanthin content, abscisic acid concentration, floral organ identity, photosynthetic rate, and root morphology.
