Predicted to enable several functions, including collagen binding activity; fibronectin binding activity; and serpin family protein binding activity. Acts upstream of or within negative regulation of mitotic cell cycle and trophoblast giant cell differentiation. Located in several cellular components, including Golgi apparatus; endosome; and lysosome. Is expressed in embryo; extraembryonic component; heart; placenta; and primary trophoblast giant cell. Human ortholog(s) of this gene implicated in hypertrophic cardiomyopathy. Orthologous to human CTSL (cathepsin L). [provided by Alliance of Genome Resources, Apr 2022]
