Abstract:
An isolated nucleic acid molecule consisting of a polynucleotide having a nucleotide sequence at least 90% identical to a sequence selected from the group consisting of:(a) a nucleotide sequence encoding a polypeptide comprising amino acids from 4 to 65 in SEQ ID NO:2 (FIG. 1); (b) a nucleotide sequence encoding a polypeptide comprising amino acids from 4 to 70 in SEQ ID NO:2 (FIG. 1); (c) a nucleotide sequence encoding a polypeptide comprising amino acids from 4 to 75 in SEQ ID NO:2; and (d) a nucleotide sequence complementary to any of the nucleotide sequences in (a), (b), or (c); and optionally, a heterologous polynucleotide sequence, wherein said nucleic acid sequence is preferentially expressed in mature B cells.
