Rabbit anti-Human LNX1 Polyclonal Antibody

Uniprot Id

Q8TBB1

Target Species

Human

Target Name

LNX1

Target Full Name

E3 ubiquitin-protein ligase LNX

Target Function

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.

Target Subcellular Location

Cytoplasm.

Target Tissue Specificity

Expressed in heart, placenta, kidney, pancreas and brain.

Target Background

This gene encodes a membrane-bound protein that is involved in signal transduction and protein interactions. The encoded product is an E3 ubiquitin-protein ligase, which mediates ubiquitination and subsequent proteasomal degradation of proteins containing phosphotyrosine binding (PTB) domains. This protein may play an important role in tumorogenesis. Alternatively spliced transcript variants encoding distinct isoforms have been described. A pseudogene, which is located on chromosome 17, has been identified for this gene.
