Summary: Enables 3-oxo-5-alpha-steroid 4-dehydrogenase activity; NADPH binding activity; and amide binding activity. Involved in several processes, including androgen metabolic process; forebrain development; and reproductive structure development. Located in cell body fiber; neuronal cell body; and perinuclear region of cytoplasm. Used to study prostate cancer. Biomarker of hyperprolactinemia; hypothyroidism; obesity; prostate cancer; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in prostate cancer and prostatic hypertrophy. Orthologous to human SRD5A1 (steroid 5 alpha-reductase 1). [provided by Alliance of Genome Resources, Dec 2024]

Ziram inhibited SRD5A1 and AKR1C14 activities, thus possibly interfering with neurosteroid production in rats.
Title: Ziram inhibits rat neurosteroidogenic 5α-reductase 1 and 3α-hydroxysteroid dehydrogenase.
Exposure of middle-aged rats to environmental enrichment increased mRNA levels of 5al;pha-reductase-1, 3alpha-HSD and cytochrome P450 17alpha-hydroxylase/c17,20-lyase and decreased the methylation state of the 5alpha-reductase-1 gene
Title: Environmental enrichment attenuates the age-related decline in the mRNA expression of steroidogenic enzymes and reduces the methylation state of the steroid 5α-reductase type 1 gene in the rat hippocampus.
The effects of deficiency or inhibition of S5AR1 on the risk of liver disease and insulin resistance in male rats and mice are reported.
Title: 5α-Reductase type 1 deficiency or inhibition predisposes to insulin resistance, hepatic steatosis, and liver fibrosis in rodents.
Low Srd5a1 expression is associated with benign prostatic hypertrophy.
Title: Bisphenol A exposure during adulthood alters expression of aromatase and 5α-reductase isozymes in rat prostate.
Changes in the expression of steroid 5-alpha reductase isoenzymes in the prostate in response to environmental stress.
Title: Expression of steroid 5α-reductase isozymes in prostate of adult rats after environmental stress.
Tesosterone concentrations during postnatal sexual differentiation of the rat central nervous system, among other sex-dependent factors, influence brain levels of 5alpha-Reductase isozymes in adulthood
Title: Steroid 5α-reductase in adult rat brain after neonatal testosterone administration.
Elevated levels of 5alpha-reduced androgens seen in hyperinsulinemic conditions might be explained on the basis of a stimulatory effect of insulin on 5alpha-reductase in granulosa cells.
Title: Stimulatory effect of insulin on 5alpha-reductase type 1 (SRD5A1) expression through an Akt-dependent pathway in ovarian granulosa cells.
Thus, the present results indicate that the vitamin E-induced regulation of SRD5A1 and GCLM in rat liver is not directly mediated by changes in promoter DNA methylation.
Title: Dietary vitamin E deficiency does not affect global and specific DNA methylation patterns in rat liver.
Data suggest that Sp1 and Sp3 play a role in the regulation of 5alpha-R gene expression, and hence the production of 5alpha-reduced neurosteroids in glial cells.
Title: Trichostatin A stimulates steroid 5alpha-reductase gene expression in rat C6 glioma cells via a mechanism involving Sp1 and Sp3 transcription factors.
Our results suggest that 5AR inhibitors elicit antipsychotic-like effects in animals and may be proposed as a putative novel target in the management of psychotic disorders.
Title: Antipsychotic-like properties of 5-alpha-reductase inhibitors.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
