Enables MAP-kinase scaffold activity; kinase binding activity; and protein kinase activator activity. Involved in several processes, including cell surface receptor protein tyrosine kinase signaling pathway; open tracheal system development; and positive regulation of intracellular signal transduction. Predicted to be active in cytoplasm. Is expressed in spermatozoon. Human ortholog(s) of this gene implicated in breast adenocarcinoma. Orthologous to several human genes including KSR1 (kinase suppressor of ras 1).
FB Description
kinase suppressor of ras (ksr) encodes a MAP-kinase scaffold protein. It mediates the activation of the serine/threonine kinase encoded by Dsor1.
