A process that directly activates any of the steps required for cell death by apoptosis.

Upregulation of the activity of a caspase, any of a group of cysteine proteases involved in apoptosis.

Any process that modulates the frequency, rate or extent of smooth muscle contraction.

A process leading to shortening and/or development of tension in striated muscle tissue.

regulation of striated muscle contraction

Any process that modulates the frequency, rate or extent of striated muscle contraction.

The joining of two lipid bilayers to form a single membrane.

induction by virus of cell-cell fusion in host

The process of syncytia-forming cell-cell fusion, caused by a virus.

The formation of a syncytium, a mass of cytoplasm containing several nuclei enclosed within a single plasma membrane. Syncytia are normally derived from single cells that fuse or fail to complete cell division.

substrate-bound cell migration, cell extension

The formation of a cell surface protrusion, such as a lamellipodium or filopodium, at the leading edge of a migrating cell.

substrate-bound cell migration, cell attachment to substrate

The formation of adhesions that stabilize protrusions at the leading edge of a migrating cell; involves integrin activation, clustering, and the recruitment of structural and signaling components to nascent adhesions.

substrate-bound cell migration, cell contraction

The translocation of the cell body forward during cell migration; mediated by tractional force on its substrate and ension in the cortical cytoskeleton ; adhesions transmit propulsive forces and serve as traction points over which the cell moves.

The process by which the structures of an oocyte are generated and organized. This process occurs while the initially relatively unspecialized cell is acquiring the specialized features of an oocyte.

Interacting selectively with intracellular fibroblast growth factor 2.

The directed movement of a motile cell or organism in response to a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis).
