Immunohistochemical staining of human testis with TGFBR3 polyclonal antibody (Cat # PAB20417) shows strong cytoplasmic positivity in Leydig cells and weak staining in cells of seminiferus ducts at 1:50-1:200 dilution.
Transforming growth factor (TGF)-beta is a multifunctional cytokine that modulates several tissue development and repair processes, including cell differentiation, cell cycle progression, cellular migration, adhesion, and extracellular matrix production. Three TGF-beta forms are encoded by separate genes: TGFB1 (MIM 190180), TGFB2 (MIM 190220), and TGFB3 (MIM 190230). The diverse effects of TGF-beta are mediated by the TGF-beta receptors and cell surface-binding proteins. Three TGF-beta receptors exist: type I (TGFBR1; MIM 190181), type II (TFGBR2; MIM 190182), and type III (TGFBR3). TGFBR3 is a glycoprotein that binds TGFB and exists in both a membrane-bound and a soluble form (Johnson et al., 1995 [PubMed 8530052]).[supplied by OMIM
