== Function ==
[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.
