GO:0031032

actomyosin structure organization

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures containing both actin and myosin or paramyosin. The myosin may be organized into filaments.

negative regulation of vascular smooth muscle cell proliferation

Any process that stops, prevents or reduces the frequency, rate or extent of vascular smooth muscle cell proliferation.

GO:0005856

cytoskeleton

Any of the various filamentous elements that form the internal framework of cells, and typically remain after treatment of the cells with mild detergent to remove membrane constituents and soluble components of the cytoplasm. The term embraces intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles.

IDA

CC

GO:0005925

focal adhesion

Small region on the surface of a cell that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments.

IDA

MF

GO:0003779

actin binding

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

GO:0005516

calmodulin binding

Interacting selectively and non-covalently with calmodulin, a calcium-binding protein with many roles, both in the calcium-bound and calcium-free states.
