Medicine® Printer-friendly version   Reviewed June 2012  What is
the official name of the PQBP1 gene?  The official name of this
gene is “polyglutamine binding protein 1.”  PQBP1 is the gene's
official symbol. The PQBP1 gene is also known by other names,
listed below.  Read more about gene names and symbols on the
About page.  What is the normal function of the PQBP1 gene?  The
PQBP1 gene provides instructions for making a protein called
polyglutamine-binding protein 1. This protein attaches (binds)
to stretches of multiple copies of a protein building block
(amino acid) called glutamine in certain other proteins.  While
the specific function of polyglutamine-binding protein 1 is not
well understood, it is believed to play a role in processing and
transporting RNA, a chemical cousin of DNA that serves as the
genetic blueprint for the production of proteins.  In nerve
cells (neurons) such as those in the brain, polyglutamine-
binding protein 1 is fo
