Predicted to enable chromatin DNA binding activity. Acts upstream of or within several processes, including blood vessel endothelial cell migration involved in intussusceptive angiogenesis; regulation of extracellular matrix organization; and skeletal muscle cell differentiation. Located in nuclear envelope. Is expressed in several structures, including allantois; foregut diverticulum endoderm; lateral plate mesoderm; neural plate; and primitive streak. Human ortholog(s) of this gene implicated in Buschke-Ollendorff syndrome. Orthologous to human LEMD3 (LEM domain containing 3). [provided by Alliance of Genome Resources, Apr 2022]
