The process by which the edges of the neural plate thicken and move up to form a U-shaped structure called the neural groove.

Catalysis of the reaction: L-arginine + H2O = L-ornithine + urea.

The last step in the formation of the neural tube, where the paired neural folds are brought together at the dorsal midline.

protein insertion into mitochondrial membrane during induction of apoptosis

protein insertion into mitochondrion membrane during induction of apoptosis

The process by which a protein is incorporated into a mitochondrial membrane as an early step in apoptosis.

Catalysis of the reaction: ATP + L-citrulline + L-aspartate = AMP + diphosphate + (Nw-L-arginino)succinate.

Catalysis of the reaction: N-(L-arginino)succinate = fumarate + L-arginine.

Interacting selectively with an opsonin, such as a complement component or antibody, deposited on the surface of a bacteria, virus, immune complex, or other particulate material.

Catalysis of the reaction: NADH + a quinone = NAD+ + a quinol.

Catalysis of the reaction: L-arginyl-tRNA + protein = tRNA + L-arginyl-protein.

The chemical reactions involving pigment, any general or particular coloring matter in living organisms, e.g. melanin.

Catalysis of the reaction: L-tryptophan = tryptamine + CO2.

Any process that modulates the frequency, rate or extent of endocytosis.

A myosin complex containing a class I myosin heavy chain and associated light chains; myosin I heavy chains are single-headed, possess tails of various lengths, and do not self-associate into bipolar filaments; myosin I complexes are involved in diverse processes related to membrane traffic and cell movement.

Interacting selectively with any component or product of the complement cascade.

Catalysis of the reaction: acetyl-CoA + an aralkylamine = CoA + an N-acetylaralkylamine.

negative regulation of natural killer cell activity

Any process that stops, prevents or reduces the rate of natural killer cell activity.

The chemical reactions involving any hormone, naturally occurring substances secreted by specialized cells that affects the metabolism or behavior of other cells possessing functional receptors for the hormone.
