Jak2

Enables several functions, including insulin receptor substrate binding activity; phosphatidylinositol 3-kinase binding activity; and signaling receptor binding activity. Involved in several processes, including cell surface receptor signaling pathway; regulation of apoptotic process; and regulation of biosynthetic process. Located in euchromatin. Is active in glutamatergic synapse and postsynapse. Used to study several diseases, including hyperuricemia; liver disease (multiple); retinal detachment; thrombocytosis; and transient cerebral ischemia. Biomarker of atherosclerosis; gastrointestinal system cancer (multiple); heart disease; liver cirrhosis; and obesity. Human ortholog(s) of this gene implicated in several diseases, including gastrointestinal system cancer (multiple); hematologic cancer (multiple); hepatic vascular disease (multiple); inflammatory bowel disease (multiple); and lung non-small cell carcinoma (multiple). Orthologous to human JAK2 (Janus kinase 2). [provided by Alliance of Genome Resources, Apr 2025]

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 Jak2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
