Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting,

Specificity / Sensitivity

CENP-E Antibody recognizes endogenous levels of total CENP-E protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val1897 of human CENP-E protein. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from U-2 OS cells treated with Nocodazole #2190 (10 nM, 16 hr) and released from mitosis into fresh medium for indicated times using CENP-E Antibody (upper) and α-Actinin (D6F6) XP® Rabbit mAb #6487 (lower).

Western Blotting

Western Blotting

Western blot analysis of extracts from HT-29 cells, untreated (-) or synchronized in mitosis by treatment with Nocodazole #2190 (10 nM, 16 hr; +), using CENP-E Antibody (upper) and α-Actinin (D6F6) XP® Rabbit mAb #6487 (lower).


Centromere-associated protein E (CENP-E) is a kinesin-like motor protein and mitotic-checkpoint kinase BUB1B binding partner that is essential for establishing and maintaining stable attachments between mitotic chromosomes and spindle microtubules (1). CENP-E plays an important role as a motor protein in the alignment of chromosomes during prometaphase (2). Research studies indicate that CENP-E protein expression peaks in late G2 and M-phases of the cell cycle before the protein is degraded at mitotic exit (3). Additional studies show that the loss of CENP-E function results in cell cycle arrest in mitosis. Mutations in the corresponding CENPE gene can result in autosomal recessive primary microcephaly-13, a developmental disorder characterized by small head circumference, dysmorphic facial features, short stature, and delayed psychomotor development (4). Since CENP-E is essential for mitotic progression and is required for cellular proliferation, it has become an interesting target for cancer therapy (5-7).
