Abstract
The present invention relates to BCL-xγ, a novel isoform of the BCL-x family of proteins which is predominantly expressed in T-lymphocytes and is associated with resistance to apoptosis. Both compositions of matter and methods are described which are useful in the treatment or prevention of immune system disorders.
Claims18
An isolated nucleic acid molecule comprising a nucleotide sequence encoding an anti-apoptotic polypeptide wherein said nucleotide sequence hybridizes to the complement of the nucleotide sequence set forth in SEQ ID NO:1 in 6×SSC at 45° C., followed by one or more washes in 0.2×SSC, 0.1% SDS at 50-65° C. and encodes a polypeptide comprising an amino acid sequence shown in amino acids 185-235 of SEQ ID NO:2.
An isolated nucleic acid molecule comprising a nucleotide sequence that hybridizes under conditions of 6×SSC at 45° C., followed by one or more washes in 0.2×SSC, 0.1% SDS at 50-65° C. to at least nucleotides 930-1082 of SEQ ID NO:1, or a complement thereof, wherein said nucleotide sequence specifically detects a BCL-xγ nucleic acid molecule relative to a nucleic acid molecule encoding another BCL-x molecule.
An isolated nucleic acid molecule comprising nucleotides 378-1082 of SEQ ID NO:1 or a complement thereof.
An isolated nucleic acid molecule comprising a transcriptional regulatory sequence comprising nucleotides 1-164 of SEQ ID NO:1.
