Corneodesmosin (CDSN, S Protein) (Biotin)

CDSN (Corneodesmosin; also S protein) is a 52-56kD, secreted glycoprotein that has an unusually high content of Gly, Pro and Ser. It is found in the desmosomes of spinous layer keratinocytes, and presumably uses its high Gly content to generate homophilic noncovalent intercellular bridges. Mature human CDSN is 497aa in length. It contains a Ser-rich region (aa62-464) and one Gly-rich domain (aa60-171). CDSN undergoes sequential proteolytic processing to generate multiple fragments that vary in size from 46-43kD, to 35-30kD, to 15kD. This sequential extracellular processing allows initially for CDSN incorporation into a functional adhesional junction, and later for the removal of adhesional glycine loops with a subsequent dissociation (desquamation) of cells. There is one potential isoform termed the S protein that shows a two aa substitution for the C-terminal 29aa. Over aa33-529, human CDSN shares 68% aa identity with mouse CDSN.\n\nApplications:\nSuitable for use in Western Blot.
