Polyglutamine-binding protein 1 is a protein that in humans is encoded by the PQBP1 gene.[1][2][3]

It can be associated with Renpenning's syndrome.

Function

PQBP1 is a nuclear polyglutamine-binding protein that contains a WW domain (Waragai et al., 1999).[supplied by OMIM][4]

Interactions

PQBP1 has been shown to interact with:
