General description

LRSAM1 is a multifunctional RING finger protein that selectively regulates cell adhesion molecules, has ubiquitin ligase activity, and plays a role in receptor endocytosis and viral budding (Li et al., 2003 [PubMed 14635195]; Amit et al., 2004 [PubMed 15256501]).[supplied by OMIM

Biochem/physiol Actions

LRSAM1 (leucine-rich repeat and sterile α motif-containing protein 1) is an E3 type ubiquitin ligase involved in membrane vesicle fusion during viral maturation and neuronal adhesion during muscle control activity. It binds to Tsg101 (tumor susceptibility gene 101) to ubiquitinate it, which further inactivates Tsg101-mediated sorting of endocytic (epidermal growth factor receptors) and exocytic (viral proteins) cargoes. It also protects cytoplasm from invasive pathogens by participating in ubiquitination associated with intracellular bacteria. Mutations in LRSAM1 cause Charcot-Marie-Tooth (CMT) disease.
