Overview of Gene Research
POLR3H is a subunit of RNA polymerase III, which transcribes small untranslated RNAs like 5S ribosomal RNA, transfer RNAs, and U6 small nuclear RNA, contributing to RNA maturation and translation. It is associated with pathways related to ovarian development and function, and its study in genetic models can offer insights into its role in biological processes and diseases [2].
In mice, loss-of-function Polr3h mutation caused early embryonic lethality. Homozygous point mutation (Polr3hD50G) in mice led to delayed pubertal development, decreased fertility later in life, decreased expression of ovarian Foxo3a, and lower numbers of primary follicles. These findings suggest that POLR3H is crucial for normal pubertal development and fertility in mice [1].
In conclusion, POLR3H plays an essential role in processes related to pubertal development and fertility as revealed through mouse models. Its study in KO mouse models has provided insights into its role in primary ovarian insufficiency, expanding our understanding of the molecular pathways of ovarian function and human infertility [1].
