CATEGORY

enzyme

SUBCELLULAR LOCALIZATION

basic FUNCTION	serum calcium decreasing factor
	degrades all trypsin and trypsinogen isoforms with high specificity
	key regulator of activation and degradation of cationic trypsin (in the high Ca(2+) environment of the duodenum, facilitates trypsinogen activation, whereas in the lower intestines, promotes trypsin degradation as a function of decreasing luminal Ca(2+) concentrations)

CELLULAR PROCESS

protein, degradation

protein

CTRC is a physiological co-activator of proCPA1 and proCPA2 and is a key regulator of digestive zymogen activation
