NUP62: Essential component of the nuclear pore complex. The N- terminal is probably involved in nucleocytoplasmic transport. The C-terminal is probably involved in protein-protein interaction via coiled-coil formation and may function in anchorage of p62 to the pore complex. Defects in NUP62 are the cause of infantile striatonigral degeneration (SNDI); also known as infantile bilateral striatal necrosis (IBSN) or familial striatal degeneration. SNDI is a neurological disorder characterized by symmetrical degeneration of the caudate nucleus, putamen and occasionally the globus pallidus, with little involvement of the rest of the brain. The clinical features include developmental regression, choreoathetosis, dystonia, spasticity, dysphagia, failure to thrive, nystagmus, optic atrophy and mental retardation. Belongs to the nucleoporin NSP1/NUP62 family.
