Interacting selectively with a cobalt (Co) ion.

Catalysis of the reaction: (-)-limonene + NADPH + H+ + O2 = (-)-perillyl alcohol + NADP+ + H2O.

A heterodimer associated with 90S and 66S preribosomes in the nucleolus; involved in ribosomal large subunit biogenesis.

A heterodimer associated with 66S preribosomes; also found throughout the nucleoplasm; involved in ribosomal large subunit biogenesis.

A heterodimer associated with precursors of the eukaryotic small ribosomal subunit, including the 90S preribosome; involved in small subunit biogenesis.

Catalysis of the hydrolysis of a peptide bond on the carboxyl side of an aspartate residue.

Modulates the rate of GTP hydrolysis by a GTPase.

negative regulation of T cell receptor signaling pathway

negative regulation of T-lymphocyte receptor signalling pathway

Any process that stops, prevents or reduces the rate, frequency or extent of signaling pathways initiated by the cross-linking of an antigen receptor on a T cell.

positive regulation of B cell receptor signaling pathway

positive regulation of B-lymphocyte receptor signalling pathway

Any process that activates or increases the rate, frequency or extent of signaling pathways initiated by the cross-linking of an antigen receptor on a B cell.

positive regulation of T cell receptor signaling pathway

positive regulation of T-lymphocyte receptor signalling pathway

Any process that activates or increases the rate, frequency or extent of signaling pathways initiated by the cross-linking of an antigen receptor on a T cell.

Any process that modulates the frequency, rate or extent of T cell activation.

Any process that modulates the frequency, rate or extent of B cell activation.

Any process that modulates the frequency, rate or extent of cell activation, the change in the morphology or behavior of a cell resulting from exposure to an activating factor such as a cellular or soluble ligand.
