Ligatin, otherwise known as eIF2D, is a protein that in humans is encoded by the LGTN gene.{{cite journal | vauthors = Jakoi ER, Brown AL, Ho YS, Snyderman R | title = Molecular cloning of the cDNA for ligatin | journal = Journal of Cell Science | volume = 93 ( Pt 2) | issue = 2 | pages = 227–32 | date = June 1989 | doi = 10.1242/jcs.93.2.227 | pmid = 2482295 }}{{cite web | title = Entrez Gene: LGTN ligatin| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=1939}} This protein is not a component of the heterotrimeric eIF2 complex, but instead functions in different pathways of eukaryotic translation.

Function

This gene encodes a protein receptor that localizes phosphoglycoproteins within endosomes and at the cell periphery. This trafficking receptor for phosphoglycoproteins may play a role in neuroplasticity by modulating cell-cell interactions, intracellular adhesion, and protein binding at membrane surfaces. In hippocampal neurons, long-lasting down-regulation of ligation mRNA levels occurs via post-transcriptional RNA processing following glutamate receptor activation. This protein contains single PUA and SUI1 domains and these domains may function in RNA binding and translation initiation, respectively.
