Any process that modulates the frequency, rate or extent of small GTPase mediated signal transduction.

The process of coordinated growth and sprouting of blood vessels giving rise to the organized vascular system.

The process of removing one or more phosphoric residues from a protein.

The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.

The chemical reactions and pathways involving sterols, steroids with one or more hydroxyl groups and a hydrocarbon side-chain in the molecule.

Any process that stops, prevents, or reduces the frequency, rate or extent of actin depolymerization.

Any process that stops, prevents, or reduces the frequency, rate or extent of actin depolymerization.

The process in which the nascent membrane forms at the meiotic outer plaque and grows until closure occurs and forespores, or prospores, are formed.

Any process that stops, prevents, or reduces the frequency, rate or extent of Rac protein signal transduction.

The migration of an epidermal cell along or through a wound gap that contributes to the reestablishment of a continuous epidermis.

The process in which the anatomical structures of blood vessels are generated and organized. The blood vessel is the vasculature carrying blood.

Any process that initiates the activity of an inactive GTPase through the replacement of GDP by GTP.

Any process that stops, prevents or reduces the frequency, rate or extent of ruffle assembly.
