Protein attributes

Sequence length1937 AA.
Sequence statusComplete.
Protein existenceEvidence at transcript level

General annotation (Comments)

Function

Muscle contraction.

Subunit structure

Muscle myosin is a hexameric protein that consists of 2 heavy chain subunits (MHC), 2 alkali light chain subunits (MLC) and 2 regulatory light chain subunits (MLC-2).

Subcellular location

Cytoplasmmyofibril. Note: Thick filaments of the myofibrils.

Domain

The rodlike tail sequence is highly repetitive, showing cycles of a 28-residue repeat pattern composed of 4 heptapeptides, characteristic for alpha-helical coiled coils.

Each myosin heavy chain can be split into 1 light meromyosin (LMM) and 1 heavy meromyosin (HMM). It can later be split further into 2 globular subfragments (S1) and 1 rod-shaped subfragment (S2).

Sequence similarities

Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Myosin family.

Contains 1 IQ domain.

Contains 1 myosin motor domain.
