What pLDDT means and how to read it

Function

Plays a role in lysosomes movement and localization at the cell periphery acting as an effector of ARL8B. Required for ARL8B to exert its effects on lysosome location, recruits kinesin-1 to lysosomes and hence direct their movement toward microtubule plus ends. Binding to ARL8B provides a link from lysosomal membranes to plus-end-directed motility (PubMed:22172677, PubMed:24088571, PubMed:25898167, PubMed:28325809). Critical factor involved in NK cell-mediated cytotoxicity. Drives the polarization of cytolytic granules and microtubule-organizing centers (MTOCs) toward the immune synapse between effector NK lymphocytes and target cells (PubMed:24088571). Required for maintenance of the…

Subunit structure

Interacts with KLC2 (via TPR repeats) (Probable). Interacts with KIF5B (PubMed:15905402). Interacts with BORCS5 (PubMed:25898167). Interacts (via RUN domain) with ARL8B (GTP-bound form); PLEKHM1 and PLEKHM2 compete for interaction with ARL8B (PubMed:22172677, PubMed:28325809). Interacts with ARL8A (PubMed:28325809)
