Myosin light chain

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Part of the myosin II structure. Atoms in the heavy chain are colored red on the left-hand side, and atoms in the light chains are colored orange and yellow.

Myosin light chain is a subunit of myosin ^[1]

Myosin light chains are distinct and have their own properties, distinct from the heavy chains. They are not considered "myosins" but are components of the macromolecular complexes that make up the functional myosin enzymes.

Light chain: MYL1, MYL2, MYL3, MYL4, MYL5, MYL6, MYL6B, MYL7, MYL9, MYLIP, MYLK, MYLK2, MYLL1
