[[https://www.uniprot.org/uniprot/LNX1_MOUSE LNX1_MOUSE]] E3 ubiquitin-protein ligase that mediates ubiquitination and subsequent proteasomal degradation of NUMB. E3 ubiquitin ligases accept ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Mediates ubiquitination of isoform p66 and isoform p72 of NUMB, but not that of isoform p71 or isoform p65.  Isoform 2 provides an endocytic scaffold for IGSF5/JAM4. [[https://www.uniprot.org/uniprot/IGSF5_MOUSE IGSF5_MOUSE]] Provides, together with MAGI1, an adhesion machinery at tight junctions, which may regulate the permeability of kidney glomerulus and small intestinal epithelial cells. Mediates calcium-independent homophilic cell adhesion. In testis, it may function as a cell adhesion molecule rather than a tight-junction protein. It may participate in the adhesion between spermatogonia-spermatogonia, spermatogonia-Sertoli cells, and Sertoli cells-Sertoli cells.<ref>PMID:12773569</ref> <ref>PMID:16982697</ref>
