Sorting nexin-4, BAR domain (IPR037430)

Short name: SNX4_BAR

Overlapping homologous superfamilies

Domain relationships



SNX4 is involved in recycling traffic from the sorting endosome (post-Golgi endosome) back to the late Golgi. It shows a similar domain architecture as SNX1-2, among others, containing a Bin/Amphiphysin/Rvs (BAR) domain, which detects membrane curvature, C-terminal to the PX domain [PMID: 17994011]. SNX4 is implicated in the regulation of plasma membrane receptor trafficking and interacts with receptors for EGF, insulin, platelet-derived growth factor and the long form of the leptin receptor [PMID: 9819414].

This entry represents the BAR domain of SNX4 from Metazoa. BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions [PMID: 19379681].
