The invention provides isolated nucleic acids molecules, designated BAL
nucleic acid molecules, which are differentially expressed in
non-Hodgkin's lymphoma. The invention also provides antisense nucleic acid
molecules, recombinant expression vectors containing BAL nucleic acid
molecules, host cells into which the expression vectors have been
introduced, and nonhuman transgenic animals in which a BAL gene has been
introduced or disrupted. The invention still further provides isolated BAL
proteins, fusion proteins, antigenic peptides and anti-BAL antibodies.
Diagnostic methods using compositions of the invention are also provided.
