Protein arginine N-methyltransferase 5 is an enzyme that in humans is encoded by the PRMT5 gene.[3][4]

PRMT5 is a highly conserved arginine methyltransferase that translocated from the cytoplasm to the nucleus at embryonic day ~E8.5, and during preimplantation development at the ~4-cell stage.[5]

Model organisms[edit]

Model organisms have been used in the study of PRMT5 function. A conditional knockout mouse line, called Prmt5tm2a(EUCOMM)Wtsi[11][12] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.[13][14][15]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[9][16] Twenty five tests were carried out on mutant mice and two significant abnormalities were observed.[9] No homozygous mutant embryos were identified during gestation, and therefore none survived until weaning. The remaining tests were carried out on heterozygous mutant adult mice but no further abnormalities were observed.[9]

A conditional allele of Prmt5 in the mouse limb shows that it is essential for maintaining a progenitor population, as conditional mutants have limb defects [17]
