Cathepsin X acts as a monocarboxypepidase and has a strict positional and narrower substrate specificity relative to the other human cathepsins. The via activation of β2 integrin receptor Mac-1 (CD11b/CD18) active cathepsin X enhances adhesion of monocytes/macrophages to fibrinogen and regulates the phagocytosis. By activation of Mac-1 receptor cathepsin X may regulate also the maturation of dendritic cells, a process, which is crucial in the initiation of adaptive immunity. Cathepsin X activates also the other β2 integrin receptor, LFA-1 (CD11a/CD18) which is involved in the proliferation of T lymphocytes. The cleavage of C-terminal amino acids of alpha and gamma enolase by cathepsin X abolishes their neurotrophic activity affecting neuronal cell survival and neuritogenesis. Cathepsin X is a cysteine carboxypeptidase, localized predominantly in immune cells, regulating their proliferation, maturation, migration and adhesion[1][2].
