Predicted to enable microfibril binding activity and transforming growth factor beta binding activity. Involved in several processes, including cellular response to mechanical stimulus; cellular response to parathyroid hormone stimulus; and cellular response to platelet-derived growth factor stimulus. Located in several cellular components, including dendrite; neuronal cell body; and perinuclear region of cytoplasm. Part of large latent transforming growth factor-beta complex. Biomarker of glomerulonephritis and transient cerebral ischemia. Human ortholog(s) of this gene implicated in cutis laxa. Orthologous to human LTBP1 (latent transforming growth factor beta binding protein 1). [provided by Alliance of Genome Resources, Apr 2022]
