Predicted to enable antigen binding activity; carbohydrate derivative binding activity; and signaling receptor binding activity. Predicted to be involved in several processes, including complement activation, lectin pathway; elastic fiber assembly; and response to UV. Predicted to act upstream of or within cell adhesion. Located in collagen-containing extracellular matrix. Is expressed in brain; genitourinary system; respiratory system mesenchyme; and visceral pericardium. Orthologous to human MFAP4 (microfibril associated protein 4). [provided by Alliance of Genome Resources, Apr 2022]
