Abstract

Parathyroid hormone-related protein (PTH-rP) is a protein with potent parathyroid hormone (PTH)-like activity which acts on PTH receptors in bone and kidney with generation of cAMP. It was initially purified from the BEN lung tumour cell line and breast and renal carcinomas associated with hypercalcaemia (Moseley et al. 1987; Burtis et al. 1987; Strewler et al. 1987). Complementary DNA (cDNA) cloned from the BEN cell line predicted a protein of 141 amino acids and molecular weight of 16 000 daltons (Suva et al. 1987). The amino-terminal region of the protein has a high degree of homology with PTH, with identity of eight of the first thirteen amino acids in both proteins (Table 1). This structural homology may explain common effects on bone resorption, adenylate cyclase stimulation and inhibition of renal phosphate reabsorption. Genomic DNA of PTH-rP was located on chromosome 12 (Mangin et al. 1988b).
