BAK7 — Arabidopsis thaliana

Summary

AT2G13780, also known as BAK7, BKK1, or SERK4 in Arabidopsis thaliana, encodes a leucine-rich repeat receptor-like kinase with both serine/threonine and tyrosine kinase activities (EC 2.7.10.1, 2.7.11.1). The protein has transmembrane receptor signaling receptor binding and protein kinase activities. BAK7 is associated with diverse biological processes including integument development, floral organ abscission, somatic embryogenesis, stomatal closure, auxin transport, root meristem growth, and the MAPK cascade. It is linked to systemic disease resistance, innate immunity, and cell death regulation. The protein localizes to the plasma membrane and mitochondria. Associations with traits include brassinosteroid sensitivity, disease tolerance, leaf and stem senescence, root development traits (lateral root length, root thickness, root mass density), and salt tolerance. BAK7 is also associated with sporogenesis, double fertilization, and megasporogenesis.
