The function of SNX17 (sorting nexin 17, Ensembl gene identifier ENSG00000115234) is as follows. Critical regulator of endosomal recycling of numerous surface proteins, including integrins, signaling receptor and channels (PubMed:15121882, PubMed:15769472, PubMed:39587083). Binds to NPxY sequences in the cytoplasmic tails of target cargos (PubMed:21512128). Associates with retriever and CCC complexes to prevent lysosomal degradation and promote cell surface recycling of numerous cargos such as integrins ITGB1, ITGB5 and their associated alpha subunits (PubMed:22492727, PubMed:28892079, PubMed:39587083). Also required for maintenance of normal cell surface levels of APP and LRP1 (PubMed:16712798, PubMed:19005208). Interacts with membranes containing phosphatidylinositol 3-phosphate (PtdIns(3P)) (PubMed:16712798). {ECO:0000269|PubMed:15121882, ECO:0000269|PubMed:15769472, ECO:0000269|PubMed:16712798, ECO:0000269|PubMed:19005208, ECO:0000269|PubMed:21512128, ECO:0000269|PubMed:22492727, ECO:0000269|PubMed:28892079}.
