Western blot - Anti-Bub1 antibody [EPR18947] - BSA and Azide free (AB251203)

This data was developed using the same antibody clone in a different buffer formulation (ab195268).

Lanes 1- 2 : Merged signal (red and green). Green - ab195268 observed at 125 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.

ab195268 was shown to react with Bub1 in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab265145 (knockout cell lysate ab257373) was used. Wild-type HeLa and BUB1 knockout HeLa cell lysates were subjected to SDS-PAGE. ab195268 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at a 1 in 1000 Dilution and a 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye®800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye®680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Supplementary information

Bub1 protein often referred to as 'Bub1' plays a mechanical role in cell cycle regulation especially during mitosis. It is known by other names such as BUB1 mitotic checkpoint serine/threonine kinase. Bub1 has a molecular mass of approximately 120 kDa. This protein is expressed in various tissues with higher levels in rapidly dividing cells. The location of its action is mainly the nucleus where it associates with kinetochores during cell division functioning in the spindle assembly checkpoint.
Biological function summary

Bub1 protein acts as a serine/threonine-protein kinase that is essential for proper chromosome segregation. It forms part of the spindle checkpoint complex along with other proteins such as BubR1 and Mad2. This complex ensures that chromosomes are correctly attached to the spindle microtubules before anaphase begins. Bub1's kinase activity contributes to the prevention of premature anaphase onset thereby helping maintain genomic stability.

Pathways

Bub1 is significantly involved in the mitotic checkpoint pathway and the cell cycle control pathway. Within these pathways Bub1 interacts closely with proteins like CDC20 and APC/C which are integral parts of the anaphase-promoting complex. Bub1 modifies the activity of these proteins to delay anaphase onset until all chromosomes are properly aligned ensuring the fidelity of cell division.

Bub1 protein shows a connection to various cancer types notably breast cancer and colorectal cancer. Defects or overexpression in Bub1 can disrupt the spindle assembly checkpoint leading to chromosome missegregation and aneuploidy hallmarks of cancerous cells. Bub1 is also linked to other spindle checkpoint proteins such as Mad1 and Bub3. Malfunction in any of these proteins including Bub1 can contribute to tumorigenesis due to impaired cell cycle control.

Target data

Serine/threonine-protein kinase that performs 2 crucial functions during mitosis : it is essential for spindle-assembly checkpoint signaling and for correct chromosome alignment. Has a key role in the assembly of checkpoint proteins at the kinetochore, being required for the subsequent localization of CENPF, BUB1B, CENPE and MAD2L1. Required for the kinetochore localization of PLK1. Required for centromeric enrichment of AUKRB in prometaphase. Plays an important role in defining SGO1 localization and thereby affects sister chromatid cohesion. Promotes the centromeric localization of TOP2A (PubMed : 35044816). Acts as a substrate for anaphase-promoting complex or cyclosome (APC/C) in complex with its activator CDH1 (APC/C-Cdh1). Necessary for ensuring proper chromosome segregation and binding to BUB3 is essential for this function. Can regulate chromosome segregation in a kinetochore-independent manner. Can phosphorylate BUB3. The BUB1-BUB3 complex plays a role in the inhibition of APC/C when spindle-assembly checkpoint is activated and inhibits the ubiquitin ligase activity of APC/C by phosphorylating its activator CDC20. This complex can also phosphorylate MAD1L1. Kinase activity is essential for inhibition of APC/CCDC20 and for chromosome alignment but does not play a major role in the spindle-assembly checkpoint activity. Mediates cell death in response to chromosome missegregation and acts to suppress spontaneous tumorigenesis.
