Lct - lactase Gene

Also Known as Lph

Species: Rattus norvegicus

Gene Type: protein coding
Gene ID: 116569

Summary

Enables lactase activity and transferase activity. Involved in several processes, including response to estrogen; response to iron(II) ion; and response to lead ion. Located in brush border. Used to study diarrhea. Biomarker of colitis. Human ortholog(s) of this gene implicated in congenital lactase deficiency. Orthologous to human LCT (lactase).
