Notes: Katacalcin is an endogenous peptide (121-141) encoded by the CALCA gene and is expressed in, and secreted from, thyroid parafollicular cells in humans.{51457} Unlike calcitonin (Item No. 24409), a calcium regulating peptide hormone, katacalcin does not affect serum calcium levels. Plasma levels of katacalcin are increased in patients with medullary thyroid carcinoma.{51458}
