UniProtKB - Q5R9Q3 (GPM6A_PONAB)
Protein
Neuronal membrane glycoprotein M6-a
Gene
GPM6A
Organism
Pongo abelii (Sumatran orangutan) (Pongo pygmaeus abelii)
Status
Functioni
Involved in neuronal differentiation, including differentiation and migration of neuronal stem cells. Plays a role in neuronal plasticity and is involved in neurite and filopodia outgrowth, filopodia motility and probably synapse formation. GPM6A-induced filopodia formation involves mitogen-activated protein kinase (MAPK) and Src signaling pathways. May be involved in neuronal NGF-dependent Ca2+ influx. May be involved in regulation of endocytosis and intracellular trafficking of G-protein-coupled receptors (GPCRs); enhances internalization and recycling of mu-type opioid receptor (By similarity).By similarity
