SR33 (TRAESCS2B02G180200) — triticum aestivum

Summary

TRAESCS2B02G180200 (symbol SR33) on bread wheat chromosome 2B encodes an RRM domain-containing protein with cis-trans proline isomerase activity, RNA binding, protein kinase activity, and identical protein binding activity. It is associated with spliceosomal complex assembly, regulation of alternative mRNA splicing, mRNA processing, protein folding and unfolding, and responses to heat, high light intensity, hydrogen peroxide, salinity, and ER stress. The gene is associated with stem rust, wheat leaf rust disease response, oxidative stress response, salt tolerance, photosynthetic rate, chloroplast development, flowering time, root development, seedling growth and development, anthocyanin content, and flower and silique morphology traits. It localizes to the nucleus, nucleolus, cytoplasm, cytosol, mitochondria, and nuclear speck. Related genes in other species link the family to ABA sensitivity, seed germination, and salt stress tolerance.
