Tet2 - tet methylcytosine dioxygenase 2

Enables methylcytosine dioxygenase activity. Involved in cellular protein modification process; myeloid cell differentiation; and positive regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including DNA demethylation; animal organ development; and hematopoietic stem cell homeostasis. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Is expressed in several structures, including brain; extraembryonic component; lower urogenital tract; reproductive system; and urethra epithelium. Human ortholog(s) of this gene implicated in gastrointestinal system cancer (multiple); hematologic cancer (multiple); lung non-small cell carcinoma; and primary immunodeficiency disease. Orthologous to human TET2 (tet methylcytosine dioxygenase 2). [provided by Alliance of Genome Resources, Apr 2022]
