WebDec 1, 1999 · PTHrP, however, differs from PTH in three important aspects: first, it is synthesized and released by various normal and malignant tissues; second, in comparison with PTH, it is elongated at its COOH-terminal end; and third, it acts in many tissues as a paracrine or autocrine factor rather than as a classical hormone. Webterminus (ie, the whole molecule and PTH-N) are biologically active. The active forms have half-lives of approximately 5 minutes. The inactive PTH-C fragments, with half-lives of 24 to 36 hours, make up more than 90% of the total circulating PTH and are primarily cleared by the kidneys.
