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.[7]

Clinical significance

POP1 is also an autoantigen in patients suffering from connective tissue diseases. Mutations in the POP1 gene result in severe anauxetic dysplasia.[8]

Interactions

POP1 (gene) has been shown to interact with POP4.[9]
