Summary Introduction

To write:

The ability of myosin to walk along an actin filament can be seen with the help of a properly equipped microscope. The way such assays are usually performed and requirement of ATP these assays. The way in which these assays are used to find out the direction of myosin movement or the force produced by myosin.

Introduction:

Actin protein belongs to a family of globular and multi-functional proteins. These proteins forms microfilaments. Basically, it is present in all the eukaryotic cells (except in nematode sperm). Actin is a spherical protein which forms the thin filament in the muscle cells. Thin filaments are made up of two long chains of actin molecules. These two actin chains are twisted around each other. Each of the actin molecules bears a myosin-binding location on which a myosin head can attach or bind.
