Background | Cystatin E/M, also referred to as CST6, is a member of type 2 cysteine proteinase inhibitors of the cystatin superfamily, and inhibits papain and cathepsin B. Cystatin E is a low molecular mass secreted protein existing in both a glycosylated (17 kDa) and an unglycosylated (14 kDa) form, with two characteristic intrachain disulfide bridges. Expression of cystatin M/E is found to be restricted to the epidermis, more specifically in the stratum granulosum, sweat glands, sebaceous glands, and the hair follicles. In addition to its function as a cysteine protease inhibitor, cystatin M/E also serves as a target for cross-linking by transglutaminases. Accordingly, cystatin M/E was suggested to be involved in barrier formation and maintenance. Furthermore, studies have revealed that cystatin M/E is frequently epigenetically inactivated during breast carcinogenesis, and thus be regarded as a candidate of tumour suppressor gene. |
Description | A DNA sequence encoding the human cystatin E/M protein (NP_001314.1) (Met 1-Met 149) was expressed with a C-terminal His-tag. |
Source | HEK293 |
Predicted N Terminal | Arg 29 |
AA Sequence | Met 1-Met 149 |
Molecular Weight | The mature form of recombinant human cystatin E/M consists of 132 a.a. and predicts a molecular mass of 15 kDa. It exists as two major forms with an identical N-terminal sequence. As a result of glycosylation, rh cystatin E/M migrates as doublets with the molecular mass of approximately 15 and 21 kDa respectively in SDS-PAGE under reducing conditions. |
