This entry consists of several animal specific latexin proteins. Latexin is a carboxypeptidase A inhibitor and is expressed in a cell type-specific manner in both central and peripheral nervous systems in the rat [1]. It consists of two cystatin-like domains, consisting of an alpha-helix enveloped by a curved beta-sheet [2,3]. These domains packed against each other, forming an interface to which the enzyme is bound. This is the C-terminal domain.
