Patent ID: 6914125

Claim:
An isolated polypeptide selected from the group consisting of: (a) a polypeptide encoded by a polynucleotide comprising the sequence of SEQ ID NO:1; (b) a polypeptide comprising a polypeptide sequence encode by SEQ ID NO:2 and which is coded for by a polynucleotide which hybridizes to the complement of SEQ ID NO:1 under stringent hybridization conditions comprising overnight incubation at 42° C. in a solution comprising: 50% formamide, 5×SSC (150 mM NaCI, 15 mM trisodium citrate), 50 mM sodium phosphate (pH7.6), 5×Denhardt's solution, 10% dextran sulfate, and 20 microgram/ml denatured, sheared salmon sperm DNA; followed by washing in 0.1×SSC at about 65° C., and which has scramblase activity; (c) a polypeptide having at least 95% identity to the polypeptide sequence of SEQ ID NO:2; (d) the polypeptide sequence of SEQ ID NO:2.
