Expression, purification, crystallization and preliminary X-ray analysis of a truncated soluble domain of human glioma pathogenesis-related protein 1.

ABSTRACT: Glioma pathogenesis-related protein 1 (GLIPR1) is a member of the CAP superfamily that includes proteins from a wide range of eukaryotic organisms. The biological functions of most CAP proteins, including GLIPR1, are unclear. GLIPR1 is up-regulated in aggressive glioblastomas and contributes to the invasiveness of cultured glioblastoma cells. In contrast, decreased GLIPR1 expression is associated with advanced prostate cancer. Forced GLIPR1 overexpression is pro-apoptotic in prostate cancer cells and is being tested in clinical trials as an experimental prostate-cancer therapy. Human GLIPR1 was expressed as a truncated soluble protein (sGLIPR1), purified and crystallized. Useful X-ray data have been collected to beyond 1.9 Å resolution from a crystal that belonged to the orthorhombic space
