Acts upstream of or within negative regulation of BMP signaling pathway. Predicted to be located in extracellular region. Is expressed in several structures, including alimentary system; embryo mesenchyme; genitourinary system; neural ectoderm; and skeletal system. Human ortholog(s) of this gene implicated in megalocornea. Orthologous to human CHRDL1 (chordin like 1). [provided by Alliance of Genome Resources, Apr 2022]
