Comparison of PN-I and p36 sequences.

(A) Alignment of p36 sequences, as reported,12 with those determined for PN-I. (B) Human PN-I cDNA sequence and its encoded amino acid sequence. The first base of the translation start codon is designated +1 and the stop codon is indicated by asterisks. The 251 amino acids obtained from PN-I peptide sequencing are underlined. Residues of fragments T42 and T50 of p36 that are not aligned with PN-I peptides (panel A) are boxed in the PN-I sequence.
