Ribonucleases P/MRP protein subunit POP1 is a protein that in humans is encoded by the POP1 gene .[1] [2]
Function
POP1 is a protein subunit of two different small nucleolar ribonucleoprotein complexes: the endoribonuclease for mitochondrial RNA processing complex and the ribonuclease P complex. This protein is a ribonuclease that localizes to the nucleus and functions in pre-RNA processing.[3]
Clinical significance
POP1 is also an autoantigen in patients suffering from connective tissue diseases. Mutations in the POP1 gene result in severe anauxetic dysplasia .[4]
Interactions
POP1 (gene) has been shown to interact with POP4 .[5]
