Predicted to enable protein kinase binding activity and protein serine/threonine kinase activator activity. Involved in several processes, including negative regulation of cell differentiation; negative regulation of cell projection organization; and negative regulation of signal transduction. Acts upstream of or within several processes, including cellular response to leukemia inhibitory factor; lung development; and negative regulation of signal transduction. Located in several cellular components, including cytoskeleton; cytosol; and nucleus. Is expressed in several structures, including alimentary system; branchial arch; future brain; genitourinary system; and limb. Used to study achalasia and intestinal pseudo-obstruction. Human ortholog(s) of this gene implicated in IgA glomerulonephritis. Orthologous to human SPRY2 (sprouty RTK signaling antagonist 2). [provided by Alliance of Genome Resources, Apr 2022]
