CD98 is a multifunctional protein predicted to function as an amino acid transmembrane transporter and to have double-stranded RNA binding activity.It is involved in carboxylic acid transport and virus entry, acting upstream of the dsRNA response, suggesting that it has multiple functions.CD98 Protein, Mouse (HEK293, His) is the recombinant mouse-derived CD98 protein, expressed by HEK293 , with N-10*His labeled tag.
