Summary
Biomotile systems, like the heart, exhibit hierarchical organization. This study explores how molecular motors gain auto-oscillatory properties, challenging the traditional view of unidirectional control in muscle contraction.
Area of Science:
- Biophysics
- Cell Biology
- Biomolecular Engineering
Background:
- Biomotile systems display structural and functional hierarchy, from molecules to organs.
- Cardiac muscle contraction, essential for heartbeat, is traditionally viewed as a top-down electrical/chemical control system.
- Muscle contractile systems exhibit inherent auto-oscillatory properties, even without external regulation.
Purpose of the Study:
- To investigate the emergence of higher-ordered auto-oscillatory properties in molecular motors.
- To challenge the conventional model of unidirectional information flow in biomotile systems.
- To explore the inherent oscillatory capabilities within the hierarchy of contractile proteins.
Main Methods:
- Review of existing literature on biomotile system organization and auto-oscillation.
- Analysis of theoretical frameworks explaining molecular motor behavior.
- Discussion of experimental findings, including in vitro motility assays.
Main Results:
- Auto-oscillatory properties are inherent to contractile proteins like actin and myosin.
- Molecular motors can acquire higher-ordered oscillatory behavior through hierarchical organization.
- The traditional view of unidirectional control in muscle contraction may be incomplete.
Conclusions:
- The auto-oscillatory nature of molecular motors contributes to the emergent properties of biomotile systems.
- Understanding this inherent oscillation is key to deciphering the functional hierarchy of muscle.
- Further research is needed to fully elucidate the mechanisms driving higher-ordered oscillations in biomotile systems.

01:06Forced Oscillations
When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of such oscillators are known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic, and the displacement is determined.
01:32Microtubule Associated Motor Proteins
Eukaryotic cells have different motor proteins for transporting various cargo within the cell. These motor proteins differ based on the filament they associate with, the direction they move within the cell, and the type of cargo they transport. Motor proteins that associate with microtubules are known as microtubule-associated motor proteins. There are two families of microtubule-associated motor proteins —Kinesins and Dyneins. Both these proteins assist in the transport of cellular cargos...
01:27ATP Driven Pumps I: An Overview
ATP-driven pumps, also known as transport ATPases, are integral membrane proteins. They have binding sites for ATP located on the membrane's cytosolic side and the ion-conducting domain in the transmembrane region. These pumps use the free energy released from ATP hydrolysis to move the solutes across cell membranes against an electrochemical gradient.
There are four main types of ATP-driven pumps - P-type, V-type, F-type, and ABC transporter. All these pumps are of varying complexities and are...

01:30Oscillations In An LC Circuit
An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by
01:34ATP Driven Pumps II: P-type Pumps
The P-type pumps are a large family of integral membrane transporter ATPases. They are divided into five major types based on substrate specificity, from I to V.
A typical P-type pump has three cytosolic domains: nucleotide-binding (N), phosphorylation (P), and activator (A) domains. These domains are connected to the membrane-spanning helices by short amino acid segments. ATP hydrolysis and covalent phosphoenzyme intermediate formation are crucial parts of the catalytic cycle. At the highly...

01:13Actin Polymerization and Cell Motility
Actin is a family of globular proteins that are highly abundant in eukaryotic cells. It makes up approximately 1-5% of total cell protein concentration. Actin monomers polymerize to form a complex network of polarized filaments, the actin cytoskeleton, that plays a crucial role in many cellular processes, including cell motility, division, endocytosis, and metastasis of cancer cells.
Actin cytoskeleton dynamics can produce pushing, pulling, and resistance forces that help the cell to migrate.
