Enables mitogen-activated protein kinase kinase binding activity. Involved in several processes, including defense response to Gram-positive bacterium; positive regulation of Ras protein signal transduction; and positive regulation of vulval development. Predicted to be located in cytoplasm. Human ortholog(s) of this gene implicated in breast adenocarcinoma. Is an ortholog of human KSR1 (kinase suppressor of ras 1).
Predicted to enable serine-tRNA ligase activity and tRNA binding activity. Predicted to be involved in mitochondrial seryl-tRNA aminoacylation. Predicted to be located in cytosol and mitochondrion. Is an ortholog of human SARS2 (seryl-tRNA synthetase 2, mitochondrial).
