SUBCELLULAR LOCALIZATION

extracellular

basic FUNCTION	physiological changes leading to parturition
	acting with estrogen to produce dilatation of the birth canal in many mammals and may be involved in remodeling of connective tissues during pregnancy
	function beyond its ability to regulate collagen turnover(Samuel 2007)
	plays an important role in the regulation of airway structure and function (Samuel 2007)
