Jup Gene Summary [Rat]
Enables protein tyrosine kinase binding activity. Predicted to be involved in several processes, including cellular response to indole-3-methanol; regulation of DNA-templated transcription; and regulation of heart contraction. Predicted to act upstream of or within cell adhesion; desmosome assembly; and skin development. Located in several cellular components, including apicolateral plasma membrane; fascia adherens; and lateral plasma membrane. Human ortholog(s) of this gene implicated in cardiomyopathy (multiple); palmoplantar keratosis (multiple); renal cell carcinoma; and reproductive organ cancer (multiple). Orthologous to human JUP (junction plakoglobin). [provided by Alliance of Genome Resources, Apr 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 Jup often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
