Description

General description

Centromere-associated protein-E (CENP-E, 312 kDa) is a member of the kinesin superfamily of microtubule motor proteins and is an integral part of kinetochore corona fibers that link centromere to the spindle microtubules. CENP-E localizes to the kinetochore throughout all phases of mitotic chromosome movement from early prometaphase through anaphase A.

Immunogen

synthetic peptide corresponding to amino acids 2545-2563 located near the C-terminus of human CENP-E conjugated to KLH.

Application

Anti-CENP-E antibody produced in rabbit has been used in:

• immunoblotting
• immunofluorescence
• immunocytochemistry.

Biochem/physiol Actions

Centromere-associated protein-E (CENP-E) plays an important role in attachment of kinetochores to spindle microtubules in the alignment of chromosomes and is an essential component of mitotic checkpoint signaling cascade. It functions as a motor in the initial chromosome movement at the mitotic midzone. CENP-E is associated with minus end-directed microtubule motor activity suggesting that CENP-E might be responsible for poleward kinetochore movements in prometaphase and anaphase A. Suppression of CENP-E synthesis by antisense CENP-E yields chromosomes that are chronically mono-oriented with flattened bipolar spindles and generates spindle poles fragments. Depletion of CENP-E leads to profound checkpoint activation and long-term mitotic arrest. CENP-E has been implicated as a binding partner for the mitotic checkpoint kinase BubR1 during mitosis.
