Activity summary

Ube2B also known as ubiquitin-conjugating enzyme E2 B plays a mechanical role in the ubiquitination process. This protein carries out its function by transferring ubiquitin from an E1 enzyme to target substrates often assisted by an E3 ligase. Ube2B is a smaller protein with a mass of around 22 kDa. It shows expression in a wide range of tissues including testis and brain suggesting tissue-specific roles.

Biological function summary

The activity of Ube2B is central to the ubiquitin-proteasome pathway where it marks proteins for degradation. Ube2B operates as part of the larger ubiquitination cascade and interacts with various E3 ligases such as RNF8 which helps to mediate its target protein selectivity. This highly regulated process ensures proper cellular protein balance and is critical for maintaining cellular homeostasis.

Pathways

Ube2B has important roles in the DNA damage response and cell cycle regulation. The ubiquitin-proteasome system facilitated by Ube2B regulates the turnover of key cell cycle proteins and supports timely progression through cell cycle phases. Ube2B works closely with proteins such as RAD18 during DNA repair processes facilitating the post-replication repair of DNA lesions.

Associated diseases and disorders

The altered function or expression of Ube2B impacts specific conditions such as cancer and neurodegenerative diseases. In cancer dysregulation can lead to uncontrolled cell proliferation due to abnormal degradation of regulatory proteins. Similarly neurodegenerative disorders involve Ube2B through aggregation and clearance failures of proteins like tau or alpha-synuclein. Ube2B's interaction with these disease processes accentuates its significance in maintaining cellular health.
