UBQLN2 (ubiquilin 2) is one of the four ubiquilin proteins found in humans, which contains a ubiquitin-like domain in its N-terminal, and a ubiquitin-associated domain in its C-terminal. The central region of this protein consists of four different heat-shock chaperonin-binding domains (STI1), and a repeat domain composed of 12 PXX domains. The corresponding gene is localized to human chromosome Xp11.21, and lacks introns.

Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: UBQLN2 (ubiquilin 2) controls the degradation of proteins with ubiquitin tags. It is the only X-chromosome gene that is associated with amyotrophic lateral sclerosis (ALS), where its PXX domain is mutated. Mutations in this gene are also linked to frontotemporal type of dementia, and in mice with ALS/dementia phenotype. Mutations in this gene results in protein aggregation and dendritic spinopathy in dendritic spines. This is also accompanied with aberrant synaptic function and reduced synaptic density.
