About Jak2

Primary_assembly 1: 226,995,334-227,054,189 forward strand.mRatBN7.2:CM026974.1

This gene has 2 transcripts (splice variants), 265 orthologues, 32 paralogues and is associated with 95 phenotypes. Biased expression in Thymus (RPKM 325.), Spleen (RPKM 258.4) and 9 other tissues.

Summary

Enables several functions, including Insulin Receptor substrate binding activity; protein C-terminus binding activity; and signaling receptor binding activity. Involved in several processes, including cell surface receptor signaling pathway; positive regulation of protein transport; and regulation of apoptotic process. Located in cytosol; euchromatin; and nucleolus. Is active in glutamatergic synapse and postsynapse. Used to study several diseases, including hyperuricemia; liver disease (multiple); non-alcoholic fatty liver disease; retinal detachment; and thrombocytosis. Biomarker of 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 2022]
