Localization

mitochondrion	both calpain 1 and calpain small subunit 1, which together form mu-calpain, are present in the mitochondrial intermembrane space. The N-terminus of calpain 1 is not processed following mitochondrial import, but is removed by autolysis following calpain activation. Calpain small subunit 1 is not directly imported into mitochondria, but is imported in the presence of calpain 1. The presence of a mitochondrial targeting sequence in the N-terminal region of calpain 1 is consistent with the localization of mu-calpain to the mitochondrial intermembrane space	Homo sapiens	5739	-
