Any process that stops, prevents, or reduces the frequency, rate or extent of the activity of a transcription factor, any factor involved in the initiation or regulation of transcription.

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

Binding to a heterotrimeric G-protein.

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

Binding to a GTPase activating protein.

A protein complex that contains the survival motor neuron (SMN) protein and at least eight additional integral components, including the Gemin2-8 and Unrip proteins; the complex is found in the cytoplasm and in nuclear Gems, and is involved in spliceosomal snRNP assembly in the cytoplasm and in pre-mRNA splicing in the nucleus.

Catalysis of the reaction: (R)-pantetheine + H(2)O = (R)-pantothenate + cysteamine.

OBSOLETE. This term was not defined before being made obsolete.

Combining with a semaphorin, and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.

Binding to a DEAD/H-box RNA helicase.

Catalysis of the reaction: D-myo-inositol 1,3,4-trisphosphate + H2O = myo-inositol 1,3-bisphosphate + phosphate.

A conserved DNA recombinase mediator complex that contains two Swi5 monomers and one Sfr1 monomer in Schizosaccharomyces, or orthologs thereof (e.g. Sae3p and Mei5p in Saccharomyces).

A protein complex containing accessory proteins which bind a recombinase (e.g. Rad51) and bind single-stranded DNA (ssDNA), and promote nucleation of the recombinase onto ssDNA through facilitating recombinase-RPA exchange.

The regulated release of bile acid, composed of any of a group of steroid carboxylic acids occurring in bile, by a cell or a tissue.
