ABCB9 PrEST Antigen

Protein function: ATP-dependent low-affinity peptide transporter which translocates a broad spectrum of peptides from the cytosol to the lysosomal lumen. Displays a broad peptide length specificity from 6-mer up to at least 59-mer peptides with an optimum of 23-mers. Favors positively charged, aromatic or hydrophobic residues in the N- and C- terminal positions whereas negatively charged residues as well as asparagine and methionine are not favored. [The UniProt Consortium] Buffer: PBS and 1M Urea, pH 7.4.
