Expression vector for animal cell line and use thereof
 An animal cell line transformed with an expression vector for an animal cell, the expression vector which contains a DNA segment comprising: PA0 (a) a DNA sequence coding for a signal peptide of an animal cell-derived protein, PA0 (b) a second DNA sequence coding for a different protein from the signal protein joined downstream of said signal peptide encoding DNA sequence without causing any reading frame shift, and PA0 (c) a promoter DNA sequence capable of functioning in an animal cell, wherein the promoter sequence is positioned upstream of the signal peptide encoding DNA sequence, can produce glycosylated proteins advantageously as secretable proteins.
