cell adhesion

The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via cell adhesion molecules.

IEA

BP

GO:0030049

muscle filament sliding

The sliding of actin thin filaments and myosin thick filaments past each other in muscle contraction. This involves a process of interaction of myosin located on a thick filament with actin located on a thin filament. During this process ATP is split and forces are generated.

positive regulation of protein targeting to mitochondrion

Any process that activates or increases the frequency, rate or extent of protein targeting to mitochondrion.

IMP

CC

GO:0005829

cytosol

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

TAS

CC

GO:0030016

myofibril

The contractile element of skeletal and cardiac muscle; a long, highly organized bundle of actin, myosin, and other proteins that contracts by a sliding filament mechanism.

ISS

CC

GO:0032982

myosin filament

A protein complex containing myosin heavy chains, plus associated light chains and other proteins, in which the myosin heavy chains are arranged into a filament.

IEA

MF

GO:0003779

actin binding

Interacting selectively and non-covalently with monomeric or multimeric forms of actin, including actin filaments.

GO:0008307

structural constituent of muscle

The action of a molecule that contributes to the structural integrity of a muscle fiber.

TAS

MF

GO:0031432

titin binding

Interacting selectively and non-covalently with titin, any of a family of giant proteins found in striated and smooth muscle. In striated muscle, single titin molecules span half the sarcomere, with their N- and C-termini in the Z-disc and M-line, respectively.
