Myeloid and erythroid nuclear termination stage-specific protein (MENT) is a member of the serpin family of protease inhibitors, and participates in DNA and chromatin condensation.[1] Alongside its ability to condense chromatin, MENT is also an effective inhibitor of the proteases cathepsin K, cathepsin L, and cathepsin V, all of which are cysteine proteases.[2] As such, although MENT is structurally classified as a member of the serpin family, it is functionally termed a "cross-class inhibitor," as it is a cysteine rather than a serine protease inhibitor.
