Parathyroid Hormone-Related Protein: Evidence for Isoform- and Tissue-Specific Posttranslational Processing

Abstract excerpt

Parathyroid hormone-related protein (PTHrP) is expressed by malignant tumors and leads to the syndrome of humoral hypercalcemia of malignancy. It is also expressed by a wide variety of nonmalignant tissues, in which it appears to play distinct paracrine and/or autocrine roles. The human PTHrP gene encodes three cDNA-predicted initial translational products of 139, 141, and 173 amino acids. Most human cell lines...
