Question

What is the role of ubiquitin in host cells?

Answer 1

Ubiquitination is found to have vital role in cellular processes including DNA damage responses, endocytosis and mitosis.

Explanation:

The ubiquitin system functions in a wide variety of cellular processes including:

1) antigen processing
2) apoptosis
3) biogenesis of organelles
4) cell cycle and division
5) DNA transcription and repair
6) differentiation and development
7) immune response and inflammation
8) neural and muscular degeneration
9) morphogenesis of neural networks
10) modulation of cell surface receptors, ion channels and secretory pathways.
