A carboxyl leucine-rich region of parathyroid hormone-related protein is critical for nuclear export.

Abstract excerpt

PTHrP is an oncofetal protein with distinct proliferative and antiapoptotic roles that are affected by nucleocytoplasmic shuttling. The protein's nuclear export is sensitive to leptomycin B, consistent with a chromosome region maintenance protein 1-dependent pathway. We determined that the 109-139 region of PTHrP was involved in its nuclear export by demonstrating that a C-terminal truncation mutant, residues...
