The reference sequence was derived from EMBL:
M31951 DNA sequence by adding 1000 nt to the end of the sequence
according to Ensembl Human sequence AL355344.20.1.149490.
Human perforin mRNA. The reference sequence was derived from EMBL:
M28393 mRNA sequence by adding the first exon to the beginning
of the sequence according to Lichtenheld & Podack 1989 (Medline:
2480391).
