CENH3 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.1HG0070030, the barley CENH3 gene on chromosome 1H, encodes a histone H3/CENP-A family protein that is a structural constituent of chromatin with nucleosomal DNA binding, DNA binding, and protein heterodimerization activity. This gene is associated with kinetochore assembly, regulation of chromosome segregation, sister chromatid cohesion, mitosis, meiosis, chromosome division, DNA condensation, chromatin silencing, and seed development. It localizes to the kinetochore, nucleolus, and nucleus. Studies of related genes in other species link the CENH3 family to awn length and spike density, though these traits are not established for barley.
