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. {ECO:0000269|PubMed:15863492, ECO:0000269|PubMed:17977821, ECO:0000269|PubMed:18434309}. |ABC membrane| |ABC tran| |SMC N| |ATPase-coupled peptide transmembrane transporter activity| |peptide transmembrane transporter activity| |ATPase-coupled transmembrane transporter activity| |transmembrane transporter activity| |antigen processing and presentation of peptide antigen via MHC class I| |integral component of endoplasmic reticulum membrane| |antigen processing and presentation of peptide antigen| |antigen processing and presentation| |ATPase activity| |lysosome| |early endosome| |lysosomal membrane| |intracellular membrane-bounded organelle| |protein homodimerization activity| |ion transmembrane transport| |endoplasmic reticulum| |transmembrane transport| |ion transport| |ATP binding| |protein transport| |peptide transport| |amide transport| |establishment of protein localization| |nitrogen compound transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp59|UMK57 1μM R01 exp59]]|-1.76| |[[:results:exp226|Cerivastatin 0.15μM R05 exp226]]|-1.71| |[[:results:exp230|Epigallocatechin gallate 20μM R05 exp230]]|-1.71| No correlation found to any other genes in chemogenomics.
