Five different insert-length cDNAs encoding for soluble placental tissue protein 18 (PP18)
variants were isolated by screening a human placental cDNA library using monospecific anti-
PP18 serum. Sequence analysis of the longest clone showed that the insert contains an
open reading frame encoding for a 392 residue-long protein with a 27 amino acid
mitochondrial targeting sequence. The mature protein—designated PP18a—is 41.264 kDa
consisting of 365 residues and is identical to the previously isolated and characterized PP18 …
