TAILIEUCHUNG - Báo cáo khoa học: Crystal structure of the catalytic domain of DESC1, a new member of the type II transmembrane serine proteinase family

DESC1 was identified using gene-expression analysis between squamous cell carcinoma of the head and neck and normal tissue. It belongs to the type II transmembrane multidomain serine proteinases (TTSPs), an expanding family of serine proteinases, whose members are differentially expressed in several tissues. | ễFEBS Journal Crystal structure of the catalytic domain of DESC1 a new member of the type II transmembrane serine proteinase family I p l t ioIoỉQ 1 Rohot Ý I I 11 hr f1 2 Fflfl9 f f nri3 R 3n f iohlot 3 I 111 ntof3 OLLO J. r.

It belongs to the type II transmembrane multidomain serine proteinases TTSPs an expanding family of serine proteinases whose members are differentially expressed in several tissues. The biological role of these proteins is currently under investigation although in some cases their participation in specific functions has been reported. This is the case for enteropeptidase hepsin matriptase and corin. Some members including DESC1 are associated with cell differentiation and have been described as tumor markers. TTSPs belong to the type II transmembrane proteins that display in addition to a C-terminal trypsin-like serine proteinase domain a differing set of stem domains a transmembrane segment and a short N-terminal .
