small GTPase regulatory/interacting protein activity

Modulates the rate of GTP hydrolysis by a small monomeric GTPase.

An area of close contact between a lymphocyte (T-, B-, or natural killer cell) and a target cell formed through the clustering of particular signaling and adhesion molecules and their associated lipid rafts on both the lymphocyte and the target cell and facilitating activation of the lymphocyte, transfer of membrane from the target cell to the lymphocyte, and in some situations killing of the target cell through release of secretory granules and/or death-pathway ligand-receptor interaction.

transferase activity, transferring acyl groups, acyl groups converted into alkyl on transfer

Catalysis of the transfer of an acyl group from one compound (donor) to another (acceptor), with the acyl group being converted into alkyl on transfer.

The change in morphology and behavior of a dendritic cell resulting from exposure to a cytokine, chemokine, cellular ligand, pathogens, or soluble factor.

positive regulation of protein transport

Any process that activates or increases the rate, frequency or extent of the directed movement of a protein into, out of, within or between cells.

Stimulates the hydrolysis and exchange of guanyl nucleotides by other proteins.

The change in morphology and behavior of a microglial cell resulting from exposure to a cytokine, chemokine, cellular ligand, pathogen, or soluble factor.

Any process that modulates the frequency, rate or extent of the directed movement of a protein into, out of, within or between cells.

ARF guanyl-nucleotide exchange factor activity

Stimulates the hydrolysis and exchange of guanyl nucleotides by the GTPase ARF.

lipid particle transport along microtubule

The directed movement of a lipid particle along a microtubule, mediated by motor proteins.

A change in the morphology or behavior of a cell resulting from exposure to an activating factor such as a cellular or soluble ligand.

negative regulation of protein transport

Any process that stops, prevents or reduces the rate, frequency or extent of the directed movement of a protein into, out of, within or between cells.
