Summary: Predicted to enable DNA-directed 5'-3' RNA polymerase activity. Predicted to be involved in transcription initiation at RNA polymerase III promoter. Predicted to be located in centrosome and nucleoplasm. Predicted to be part of RNA polymerase III complex. Is expressed in several structures, including alimentary system; limb; nervous system; respiratory system; and sensory organ. Used to study primary ovarian insufficiency. Orthologous to human POLR3H (RNA polymerase III subunit H). [provided by Alliance of Genome Resources, Jan 2025]

What's a GeneRIF?

Loss-of-function Polr3h mutation in mice caused early embryonic lethality. Mice with homozygous point mutation (Polr3hD50G) were viable but showed delayed pubertal development, characterized by late first estrus or preputial separation. The Polr3hD50G female and male mice showed decreased fertility later in life, associated with small litter size and increased time to pregnancy or to impregnate a female.
Title: Exome Sequencing Reveals the POLR3H Gene as a Novel Cause of Primary Ovarian Insufficiency.
Pol III regulation in the liver thus entails both highly expressed housekeeping genes and genes whose expression can adapt to increased demand.
Title: Differential regulation of RNA polymerase III genes during liver regeneration.
Pol III transcription during the diurnal cycle is regulated both in response to nutrients and by the circadian clock, which allows anticipatory Pol III transcription.
Title: Diurnal regulation of RNA polymerase III transcription is under the control of both the feeding-fasting response and the circadian clock.

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.
