Enables extracellular matrix constituent conferring elasticity and identical protein binding activity. Involved in several processes, including negative regulation of signal transduction; regulation of extracellular matrix organization; and regulation of gene expression. Acts upstream of or within extracellular matrix organization and positive regulation of cell-substrate adhesion. Located in extracellular matrix. Is expressed in several structures, including early conceptus; embryo mesenchyme; genitourinary system; heart and pericardium; and musculoskeletal system. Orthologous to human EMILIN1 (elastin microfibril interfacer 1). [provided by Alliance of Genome Resources, Apr 2022]
