AAC1 — Oryza sativa Japonica

Summary

OsAAC1 (OS11G0163100) in rice encodes an actin protein that is a structural constituent of the cytoskeleton, possesses hydrolase activity, and binds ATP. This gene is associated with a wide range of biological processes, including nucleotide-sugar, sulfur, sucrose, and one-carbon metabolism, thiamin and cytokinin biosynthesis, photorespiration, the TCA cycle, protein processing, the ERAD pathway, DNA integration, cell fate determination, asymmetric cell division, root hair elongation, regeneration, hypersensitivity, and the response to cadmium. It is localized to the actin cytoskeleton and nucleus. OsAAC1 has been linked to several agronomically important traits, including grain number, size, weight, and yield, as well as leaf angle, amino acid content, and drought tolerance. Studies of related genes in other species further connect this family to ATPase activity.
