Gene: Hmbs (hydroxymethylbilane synthase) Rattus norvegicus
Symbol: Hmbs
Name: hydroxymethylbilane synthase
CRRD ID: 2801
Description: Exhibits several functions, including amine binding activity; hydroxymethylbilane synthase activity; and uroporphyrinogen-III synthase activity. Involved in several processes, including cellular response to dexamethasone stimulus; cellular response to lead ion; and response to estradiol. Localizes to several cellular components, including axon; cytosol; and perinuclear region of cytoplasm. Colocalizes with condensed chromosome. Biomarker of bilirubin metabolic disorder and liver carcinoma. Human ortholog(s) of this gene implicated in acute intermittent porphyria and sickle cell anemia. Orthologous to human HMBS (hydroxymethylbilane synthase); PARTICIPATES IN heme biosynthetic pathway; acute intermittent porphyria pathway; erythropoietic porphyria pathway; INTERACTS WITH 1,2,4-trimethylbenzene; 17alpha-ethynylestradiol; 2,3,7,8-tetrachlorodibenzodioxine.
Type: protein-coding
RefSeq Status: VALIDATED
