OBSOLETE. Any process that terminates the activity of the active enzyme MAP kinase kinase kinase (MAPKKK).

Any process that activates or increases the frequency, rate or extent of the activity of the nerve growth factor (NGF) receptor.

Any process that modulates the frequency, rate or extent of the activity of the nerve growth factor (NGF) receptor.

Any process that stops, prevents, or reduces the frequency, rate or extent of the activity of the nerve growth factor (NGF) receptor.

OBSOLETE. Catalysis of the hydrolysis of a lysine residue from the N-terminal of an oligopeptide or polypeptide chain.

OBSOLETE. Catalysis of the hydrolysis of basic amino acid residues at the N-terminal of an oligopeptide or polypeptide chain.

Catalysis of the reaction: acetyl-CoA + cytidine = CoA + N4-acetylcytidine. The cytidine is within the polynucleotide chain of a tRNA.

The modification of tRNA structure by addition of an acetyl group to tRNA. An acetyl group is CH3CO-, derived from acetic [ethanoic] acid.

Binding to actinin, any member of a family of proteins that crosslink F-actin.

OBSOLETE. Catalysis of the hydrolysis of an arginine residue from the N-terminal of an oligopeptide or polypeptide chain.

Any process that contributes to cytokine production by a plasmacytoid dendritic cell.

Any process that contributes to cytokine production by a dendritic cell.

Any process that contributes to cytokine production by a myeloid dendritic cell.

Any process that contributes to cytokine production by a natural killer cell.

Any process that contributes to cytokine production by a B cell.

A change in morphology and behavior of a leukocyte resulting from exposure to a specific antigen, mitogen, cytokine, cellular ligand, or soluble factor, leading to the initiation or perpetuation of an immune response.
