Smad7 Gene Summary [Rat]
Enables ubiquitin protein ligase binding activity. Involved in intracellular signal transduction; negative regulation of DNA-templated transcription; and regulation of transforming growth factor beta receptor signaling pathway. Predicted to be located in several cellular components, including adherens junction; microtubule organizing center; and nuclear lumen. Predicted to be part of heteromeric SMAD protein complex. Predicted to be active in plasma membrane. Biomarker of nephritis and pulmonary hypertension. Human ortholog(s) of this gene implicated in colorectal cancer and pancreatic adenocarcinoma. Orthologous to human SMAD7 (SMAD family member 7). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Smad7 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
