LGTN

Ligatin, otherwise known as eIF2D, is a protein that in humans is encoded by the LGTN gene.[5][6] 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.[6]
