RP1 — Zea mays

Summary

ZmRP1 (RP1) on maize chromosome 2 encodes a 60S ribosomal protein L3, a structural constituent of the ribosome, and is also associated with SUMO transferase activity, SUMO binding, kinase binding, ATP hydrolase activity, and RNA binding. The gene is directly linked to resistance to maize rust. It has been associated with gene conversion, metaphase, interphase, regulation of actin polymerization, nuclear movement, electron transport chain, membrane fusion, vacuolar protein sorting, cell morphogenesis, meiosis, autophagy, double fertilization, calcium signaling, and meristem growth. Associations with traits include tassel branch number, zinc sensitivity, stem rust, leaf angle, flowering time, plant height, and disease tolerance. The protein localizes to the cytosolic large ribosomal subunit, proteasome, ribosome, nucleolus, and vacuole. Related genes in other species are linked to zinc deficiency tolerance and embryo viability.
