Summary
Centromere-associated protein E (CENP-E) is crucial for mitosis and a cancer therapy target. New research shows TRAMM protein is key in recruiting CENP-E to kinetochores during cell division.
Area of Science:
- Cell Biology
- Molecular Biology
- Cancer Therapeutics
Background:
- Mitosis is a fundamental cell division process regulated by checkpoints for accurate chromosome distribution.
- Centromere-associated protein E (CENP-E) is vital during mitosis and represents a promising target for anti-cancer drug development.
Purpose of the Study:
- To investigate the role of the protein TRAMM (trafficking of membranes and mitosis) in the cellular localization of CENP-E.
- To understand the molecular mechanisms underlying CENP-E recruitment to kinetochores.
Main Methods:
- Immunofluorescence microscopy to visualize protein localization.
- Biochemical assays to study protein interactions.
- Cell-based assays to assess mitotic progression and chromosome alignment.
Main Results:
- The protein TRAMM was found to be involved in the recruitment of CENP-E to kinetochores.
- TRAMM plays a significant role in ensuring proper CENP-E localization during mitosis.
Conclusions:
- TRAMM is implicated as a critical factor in the kinetochore targeting of CENP-E.
- Targeting the TRAMM-CENP-E interaction could offer novel therapeutic strategies for cancer treatment.

02:30Histone Variants at the Centromere
5.2K
Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3...

Translocation of proteins across membranes is an ancient process that occurs even in bacteria and archaebacteria. In fact, the components of the translocation machinery are still conserved between prokaryotes and eukaryotes.

02:25Centrosome Duplication
5.1K
The primary microtubule organizing center (MTOC) in animal cells is the centrosome. A centrosome has two cylindrical centrioles at its core. Each centriole consists of nine sets of three microtubules held together by proteins. The centrioles are positioned at right angles to each other and surrounded by a shapeless protein cloud called the pericentriolar matrix, or pericentriolar material (PCM).

01:13Centrioles and Centrosomes
7.1K
Most animal cells comprise a pair of centrioles together called a centrosome. The cell duplicates its centrosome and contains two centrosomes side-by-side, which begin to move apart during the prophase. As the centrosomes migrate to two different sides of the cell, microtubules start extending from each centrosome toward the other end. The mitotic spindle is composed of the centrosomes and their emerging microtubules.

The translocon complex situated on the ER membrane is the main gateway for the protein secretory pathway. It facilitates the transport of nascent peptides into the ER lumen and their insertion into the ER membrane.
Sec61 protein conducting channel
In eukaryotes, the translocon complex comprises a core heterotrimeric translocator channel called the Sec61 complex. This channel includes three transmembrane proteins, Sec61α, Sec61β, and Sec61γ, and is the largest subunit of the...
