Motor protein

motor protein

(Science: protein) proteins that bind aTP and are able to move on a suitable substrate with concomitant ATP hydrolysis.

most eukaryotic motor proteins move by binding to a specific site on either actin filaments (myosin) or on microtubules (dynein, kinesin). They are normally elongated molecules with two active binding sites although some kinesin analogues have a single site.

The distal end of the molecule normally binds adaptor proteins that enable them to make stable interactions with membranous vesicles or with filamentous structures, which then constitute the cargo to be moved along the substrate filament.

Need help brainstorming

Alright, I'm going to do a 3D representation of a motor protein moving an organelle. I'm going to talk to my prof tomorrow about it.
