Itk Gene Summary [Rat]
Predicted to enable non-membrane spanning protein tyrosine kinase activity. Predicted to be involved in several processes, including T cell activation; antigen receptor-mediated signaling pathway; and protein phosphorylation. Predicted to be located in cell-cell junction; cytosol; and nucleus. Predicted to be active in plasma membrane. Human ortholog(s) of this gene implicated in lymphoproliferative syndrome 1. Orthologous to human ITK (IL2 inducible T cell kinase). [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 Itk often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
