induction of apoptosis via death domain receptors

Catalysis of the hydrolysis of N-terminal di- or tripeptides from a polypeptide chain.

regulation of cytosolic calcium ion concentration

The regulation of the levels, transport, and metabolism of calcium ions within the cytoplasm of a cell or between the cytoplasm and its surroundings.

Any process induced by hormones that directly activates any of the steps required for cell death by apoptosis.

induction of apoptosis by intracellular signals

Any process induced by intracellular signals that directly activates any of the steps required for cell death by apoptosis.

The series of molecular signals initiated in response to osmotic change.

Catalysis of the preferential cleavage of Arg-Xaa bonds in small molecule substrates. Highly selective action to release kallidin (lysyl-bradykinin) from kininogen involves hydrolysis of Met-Xaa or Leu-Xaa. The rat enzyme is unusual in liberating bradykinin directly from autologous kininogens by cleavage at two Arg-Xaa bonds.

Catalysis of the release of an N-terminal tripeptide from a polypeptide.

Enables the directed movement of L-serine, the levorotatory isomer of 2-amino-3-hydroxypropanoic acid, into, out of, within or between cells.

osmosensory signaling pathway via two-component system

osmosensory signalling pathway via two-component system

A series of molecular signals generated in response to osmotic change, as mediated through a two-component (phosphorelay) system.

Catalysis of the preferential cleavage of Arg-Xaa, Lys-Xaa.

Enables the directed movement of tryptophan, 2-amino-3-(1H-indol-3-yl)propanoic acid, into, out of, within or between cells.

Enables the directed movement of peptides, compounds of two or more amino acids where the alpha carboxyl group of one is bound to the alpha amino group of another, into, out of, within or between cells.

Catalysis of the hydrolysis of peptide linkages in oligopeptides or polypeptides by a reaction mechanism in which threonine residues act as nucleophiles.
