Scientific Data Images for Human/Mouse Bub3 Antibody

Detection of Human/Mouse Bub3 by Western Blot.

Western blot shows lysates of Jurkat human acute T cell leukemia cell line, HeLa human cervical epithelial carcinoma cell line, 293T human embryonic kidney cell line, and NIH-3T3 mouse embryonic fibroblast cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse Bub3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5706) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Bub3 at approximately 43 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: Bub3

Bub3 (Budding uninhibited by benzimidazoles 3 homolog; also Mitotic checkpoint protein Bub3) is a 35‑40 kDa member of the WD repeat Bub3 family of molecules. It plays a key role in chromosome segregation by serving as a component of the mitotic checkpoint complex. This complex inhibits Cdc20, and E3 ubiquitin ligase that initiates the metaphase to anaphase transition, until microtubules are properly aligned with, and bound to, chromatid kinetochores. Human Bub3 is 328 amino acids (aa) in length. It contains five WD40 repeats (aa 5‑43, 46‑83, 86‑124, 128‑163 and 223‑262) plus a phosphorylation site at Ser211 and a Lys at # 216 that may form an interchain crosslink with Gly. There are two splice variants that show two or four aa deletion over the four C‑terminal amino acids. Full‑length human and mouse Bub3 share 99% aa identity.
