Cathepsin-6, a novel cysteine proteinase showing homology with and co-localized expression with cathepsin J/P in the labyrinthine layer of mouse placenta

Biochem J. 2000 Aug 1;349 Pt 3(Pt 3):689-92. doi: 10.1042/bj3490689.

Abstract

A novel cysteine proteinase, cathepsin-6, was isolated by RNA differential display from mouse placenta. Cathepsin-6 showed the highest homology with cathepsin J (same as P) and L. The structural features including the catalytic triad of the C1 proteinase family were well conserved in cathepsin-6. The expression of cathepsin-6 and cathepsin J/P was restricted in labyrinthine trophoblasts of the placenta.
