Kinesin is an ATP-dependent motor protein responsible for the transportation of cargo. It is a heterotetramer composed of light and heavy chains.

The Variant[https://www.uniprot.org/uniprot/P84243 histone H3] replaces H3 in a range of nucleosomes in active genes. Deposited at sites of nucleosomal displacement throughout transcribed genes which represents an epigenetic imprint of active chromatin. Nucleosomes wrap and compact DNA into chromatin. Also Histones play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling

in a PubMed abstract,[https://www.nature.com/articles/srep07115 CENP-A]which is a centromere-specific histone H3 variant is over expressed in cancer cells and it can be mislocalized ectopically in the form of heterotypic nucleosomes containing H3.3.

;Scene #1: Kinesin structure is composed of eight anti-parallel Beta sheets and three alpha helices on opposite sides <scene name='75/752263/Alpha_beta_sheets/5'> Alpha-beta structure </scene>

;Scene #2: This is the ATP binding site. Upon the binding of phosphate to ADP, ATP is formed giving Kinesin the energy needed to move the cargo one step a head to its destination <scene name='75/752263/Atp_binding_site/5'> ATP-binding site </scene>

;Scene #3: This is the Microtubule-binding site, where Kinesin binds to microtubules for stability <scene name='75/752263/Mt-binding_site/1'> MT-binding site </scene>

;Scene #4: some patients with CMT show mutation in the p-loop. A missense mutation results in a leucine in place of glutamine affecting signal transmission <scene name='75/752263/Cmt/1'> CMT </scene>

This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
