CIN4 — Sorghum bicolor

Summary

SORBI_3009G174900 (SbCIN4) on sorghum chromosome 9 encodes a protein with ubiquitin-conjugating enzyme activity, histone H2B deubiquitinase activity, metallopeptidase activity, metalloendopeptidase activity, chaperone protein binding, ubiquitin ligase binding, calmodulin binding, nucleic acid binding, ubiquitin ligase activity, ubiquitin-protein transferase activity, ATP hydrolase activity, protein kinase activity, and identical protein binding. The gene is associated with upregulation of proteasomal ubiquitin-dependent protein catabolic process, endosomal transport, COP9 signalosome assembly, protein polyubiquitination, protein deneddylation, regulation of photomorphogenesis, and entrainment of circadian clock. It has been linked to the stay-green trait, abscisic acid concentration, drought tolerance, leaf senescence, photoperiod-sensitive flowering time, seed dormancy, and responses to UV light, boron, zinc, and ethylene. Additional associations include stomatal closure, salt stress tolerance, disease resistance, and traits affecting root mass density, lateral root length, and chloroplast development. Related genes in other species are linked to photomorphogenesis, cold and osmotic stress tolerance, and grain weight.
