CD63 Protein

CD63 Protein Overview

CD63 reagents

The melanoma-associated antigen ME491 is expressed strongly during early stages of progression of the tumor. Hotta et al. (1988) cloned the ME491 gene by means of DNA-mediated gene transfer followed by the screening of a lambda genomic library with human repetitive Alu sequences as a probe. The cloned DNA, after transcription into mouse L-cells, generated a protein whose characteristics were indistinguishable in Western blot analysis from the ME491 antigen expressed by human melanoma cells. The sequence of the cDNA indicates that the antigen has 237 amino acids (molecular mass, 25,475 Da) with 4 transmembrane regions and 3 putative N-glycosylation sites.

CD63 protein family
