HAP4 — Oryza sativa Indica Group

Summary

BGIOSGA031297 (HAP4) on Indica rice chromosome 9 encodes a ubiquitin-like domain-containing protein with a ribosomal eL40 domain, and is annotated as a structural constituent of the ribosome, a protein tag, and an mRNA-binding protein. It is associated with translation, protein ubiquitination, modification-dependent proteolysis, DNA integration, replication, and metabolism. The gene product localizes to the cytoplasm, nucleus, ribosome, cytosolic ribosome, and ribonucleoprotein complexes. HAP4 has been linked to grain shape, grain weight, grain yield, and cold tolerance. Related genes in other species are linked to ubiquitin.
