Predicted to enable transforming growth factor beta binding activity. Predicted to be involved in elastic fiber assembly and regulation of proteolysis. Predicted to act upstream of or within hormone secretion and transforming growth factor beta receptor signaling pathway. Predicted to be located in collagen-containing extracellular matrix and microfibril. Human ortholog(s) of this gene implicated in autosomal recessive cutis laxa type IC. Orthologous to human LTBP4 (latent transforming growth factor beta binding protein 4). [provided by Alliance of Genome Resources, Apr 2022]
