NCIt definition : Peroxisomal targeting signal 1 receptor (639 aa, 71 kDa) is encoded by the human
PEX5 gene. This protein plays a role in recognition of peroxisome targeting signals
(PTS) and the transport of proteins into the peroxisome matrix.;
NCIt note : Peroxisomal targeting signal 1 receptor specifically binds to and promotes peroxisomal
translocation of proteins containing a peroxisome targeting signal type 1 (PTS1) but
it can also mediate the translocation of cargo containing PTS2 sequences via interactions
with peroxisomal targeting signal 2 receptor (PEX7). (UniProt);
