Description
Cathepsin F, also known as CTSF, belongs to the cathepsin family. Cathepsins are papain familycysteine proteinases that represent a major component of the lysosomal proteolytic system. The CTSF gene isubiquitously expressed, and it maps to chromosome 11q13, close to the gene encoding cathepsin W. CTSF isthought to play a role in normal protein catabolism, and because it is highly expressed in some cancer cell lines, itmay be involved in degradative processes occurring during tumor progression. Recombinant human CTSF protein,fused to His-tag at N-terminus, was expressed in E.coli.
