Predicted to enable several functions, including I-SMAD binding activity; Roundabout binding activity; and androgen receptor binding activity. Acts upstream of or within several processes, including epithelial cell differentiation; morphogenesis of embryonic epithelium; and negative regulation of fat cell differentiation. Located in focal adhesion. Is expressed in several structures, including bronchus; central nervous system; genitourinary system; heart; and vertebral axis musculature. Orthologous to human TGFB1I1 (transforming growth factor beta 1 induced transcript 1). [provided by Alliance of Genome Resources, Apr 2022]
