What is the normal function of the UBQLN2 gene?

From Entrez GeneThis link leads to a site outside Genetics Home Reference.:

This gene encodes an ubiquitin-like protein (ubiquilin) that shares high degree of similarity with related products in yeast, rat and frog. Ubiquilins contain a N-terminal ubiquitin-like domain and a C-terminal ubiquitin-associated domain. They physically associate with both proteasomes and ubiquitin ligases; and thus, are thought to functionally link the ubiquitination machinery to the proteasome to affect in vivo protein degradation. This ubiquilin has also been shown to bind the ATPase domain of the Hsp70-like Stch protein. [provided by RefSeq, Oct 2009]

From UniProtThis link leads to a site outside Genetics Home Reference.:

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

How are changes in the UBQLN2 gene related to health conditions?

Genetics Home Reference provides information about amyotrophic lateral sclerosis, which is associated with changes in the UBQLN2 gene.
UniProtThis link leads to a site outside Genetics Home Reference. provides the following information about the UBQLN2 gene's known or predicted involvement in human disease.

Amyotrophic lateral sclerosis 15, with or without frontotemporal dementia (ALS15)[1]This link leads to a site outside Genetics Home Reference.: 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. Note=The disease is caused by mutations affecting the gene represented in this entry.

Entrez GeneThis link leads to a site outside Genetics Home Reference. lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the UBQLN2 gene.
