Ubiquitin plays a fundamental role in cell biology as a key regulator of protein degradation and cellular processes.

More on: cell markers and ubiquitin
Ubiquitin, a small protein found in nearly all eukaryotic cells, plays a fundamental role in regulating various cellular processes. Its primary function is to mark proteins for degradation through the ubiquitin-proteasome system, a highly controlled and selective process known as ubiquitination. When a protein is destined for degradation or clearance, multiple ubiquitin molecules are covalently attached to specific lysine residues on the target protein, forming a polyubiquitin chain. This ubiquitin chain acts as a signal, directing the tagged protein to the proteasome, a large multi-subunit protein complex responsible for protein degradation. Once delivered to the proteasome, the ubiquitinated protein is unfolded and processed, and its constituent amino acids are recycled for the synthesis of new proteins. Apart from its role in protein degradation, ubiquitin also participates in various non-proteolytic functions, such as DNA repair, endocytosis, and signal transduction, where monoubiquitination or other ubiquitin modifications can serve as regulatory signals. The precise and intricate control of ubiquitin-mediated processes ensures proper cellular homeostasis, protein turnover, and the maintenance of critical cellular functions.


Formalin fixed paraffin embedded section of cerebral cortex of an Alzheimer patient processed with 1737 using HRP/ DAB, giving a brown signal. Also stained with haemotoxylin in blue. A typical flame shaped tangle is seen in a pyramidal neuron in the center and is surrounded by some dystrophic neurites, also strongly ubiquitin positive. Both are commonly seen in cortical and hippocampal Alzheimer brain sections and are typical for this disease, but are rare or absent in healthy brain.
Chromogenic immunostaining of a NBF fixed paraffin embedded human hippocampus section from an Alzheimer's Disease case. Mouse mAb to ubiquitin, 1737, dilution 1:2,000, was detected in DAB (brown) following the ImmPress method with citra buffer retrieval. Hematoxylin (blue) was used as the counterstain. The 1737 antibody strongly labels flame shapped tangles in pyramidal neurons and dystrophic neurites nuclei characteristic of Alzheimer's disease. This antibody performs well in testing with 4% PFA or standard NBF fixed human and rat tissues. Mouse select image for larger view.
Blots probed with 1737 of mono and K48 linked polyubiquitin (Boston Biotech, lane 1), monoubiquitin only (2), and 100µg total wet weight of homogenates of rat cerebellum, cortex and brain stem respectively (lanes 3-5). Material was run out on 20% SDS-PAGE and transferred electrophoretically to PVDF. 1737 binds both mono and polyubiquitin and detects monoubiquitin in cell and tissue lysates.
Western blot analysis of HEK293 cell lysates using mouse mAb to ubiquitin, 1737, dilution 1:1,000 in green. [1] protein standard (red), [2] cells maintained in normal medium, [3] cells treated with 10µM of proteasome inhibitor lactacystin (Lc) for 16hrs. Lysed cells were electrophoresed on 4-20% SDS-PAGE, and transferred to PVDF membranes. The smear detected above the 200kDa standard represent accumulation of ubiquitinated proteins in proteasome inhibitor-Lc treated cells. The prominent band at 8kDa corresponds to monoubiquitin. The same blot was probed with rabbit pAb to HSP60, 2417, dilution 1:5,000 in red, used as a loading control.
