Sorting nexin-5 is a protein that in humans is encoded by the SNX5 gene.[5][6][7]

This gene encodes a member of the sorting nexin family. Members of this family contain a phox (PX) domain, which is a phosphoinositide binding domain, and are involved in intracellular trafficking. This protein is a component of the mammalian retromer complex,[6] which facilitates cargo retrieval from endosomes to the trans-Golgi network. It has also been shown to bind to the Fanconi anemia, complementation group A protein. This gene results in two transcript variants encoding the same protein.[7]

Model organisms[edit]

Model organisms have been used in the study of SNX5 function. A conditional knockout mouse line, called Snx5tm1a(KOMP)Wtsi[13][14] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute.[15][16][17] Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[11][18] Twenty five tests were carried out on homozygous mutant adult mice, however no significant abnormalities were observed.[11]


SNX5 has been shown to interact with FANCA.[5]
