Gene: Cyp3a23/3a1 (cytochrome P450, family 3, subfamily a, polypeptide 23/polypeptide 1) Rattus norvegicus
Symbol: Cyp3a23/3a1
Name: cytochrome P450, family 3, subfamily a, polypeptide 23/polypeptide 1
Description: Exhibits demethylase activity and testosterone 6-beta-hydroxylase activity. Involved in several processes, including oxidative demethylation; response to cadmium ion; and response to glucocorticoid. Localizes to the endoplasmic reticulum membrane and intracellular membrane-bounded organelle. Biomarker of cholestasis and mental depression. Human ortholog(s) of this gene implicated in chronic myeloid leukemia; essential hypertension; precursor B lymphoblastic lymphoma/leukemia; and precursor lymphoblastic lymphoma/leukemia. Orthologous to human CYP3A5 (cytochrome P450 family 3 subfamily A member 5); PARTICIPATES IN tamoxifen pharmacokinetics pathway; linoleic acid metabolic pathway; phase I biotransformation pathway via cytochrome P450; INTERACTS WITH 1,1,1-Trichloro-2-(o-chlorophenyl)-2-(p-chlorophenyl)ethane; 1,2,4-trichlorobenzene; 1,2-dichloroethene.
Type: protein-coding
