Disease

[UBQL2_HUMAN] Defects in UBQLN2 are the cause of amyotrophic lateral sclerosis type 15 with or without frontotemporal dementia (ALS15) [MIM:300857]. A neurodegenerative disorder affecting upper motor neurons in the brain and lower motor neurons in the brain stem and spinal cord, resulting in fatal paralysis. Sensory abnormalities are absent. The pathologic hallmarks of the disease include pallor of the corticospinal tract due to loss of motor neurons, presence of ubiquitin-positive inclusions within surviving motor neurons, and deposition of pathologic aggregates. The etiology of amyotrophic lateral sclerosis is likely to be multifactorial, involving both genetic and environmental factors. The disease is inherited in 5-10% of the cases. Patients with ALS15 may develop frontotemporal dementia.[1][2][3][4]

Function

[UBQL2_HUMAN] Increases the half-life of proteins destined to be degraded by the proteasome; may modulate proteasome-mediated protein degradation.[5]
