Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).

Interacting selectively and non-covalently with a protein kinase, any enzyme that catalyzes the transfer of a phosphate group, usually from ATP, to a protein substrate.

Interacting selectively and non-covalently with a SH3 domain (Src homology 3) of a protein, small protein modules containing approximately 50 amino acid residues found in a great variety of intracellular or membrane-associated proteins.

Conveys a signal across a cell to trigger a change in cell function or state. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments. Includes processes that control the spatial distribution of actin filaments, such as organizing filaments into meshworks, bundles, or other structures, as by cross-linking.

A series of molecular signals initiated by the cross-linking of an antigen receptor on a B or T cell.

A series of molecular signals initiated by the cross-linking of an antigen receptor on a B cell.

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

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

The process resulting in the physical partitioning and separation of a cell into daughter cells.

The orderly movement of a cell from one site to another, often during the development of a multicellular organism or multicellular structure.

The multiplication or reproduction of cells, resulting in the expansion of a cell population.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a hepatocyte growth factor stimulus.

A series of molecular signals initiated by binding of a ligand to the tyrosine kinase receptor EGFR (ERBB1) on the surface of a cell. The pathway ends with regulation of a downstream cellular process, e.g. transcription.

A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, or for basal GPCR signaling the pathway begins with the receptor activating its G protein in the absence of an agonist, and ends with regulation of a downstream cellular process, e.g. transcription.

The series of molecular signals generated as a consequence of the hepatocyte growth factor receptor binding to one of its physiological ligands.

The series of molecular signals generated as a consequence of the insulin receptor binding to insulin.

A series of molecular signals initiated by the binding of extracellular ligand to an integrin on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

The series of molecular signals generated as a consequence of the nerve growth factor receptor binding to one of its physiological ligands.

The series of molecular signals generated as a consequence of a platelet-derived growth factor receptor binding to one of its physiological ligands.

Any process that activates or increases the frequency, rate or extent of cell migration.

Any process that increases the rate, frequency, or extent of the orderly movement of an endothelial cell into the extracellular matrix to form an endothelium.

Any process that modulates the occurrence or rate of cell death by apoptotic process.

Any process that modulates the frequency, rate, extent or direction of cell growth.

A series of molecular signals initiated by the cross-linking of an antigen receptor on a T cell.

Any series of molecular signals initiated by the binding of an extracellular ligand to a vascular endothelial growth factor receptor (VEGFR) located on the surface of the receiving cell, and ending with regulation of a downstream cellular process, e.g. transcription.
