negative regulation of endothelial cell proliferation

Any process that stops, prevents, or reduces the rate or extent of endothelial cell proliferation.

positive regulation of endothelial cell proliferation

Any process that activates or increases the rate or extent of endothelial cell proliferation.

The pronucleus originating from the ovum that is being fertilized.

extracellular ligand-gated ion channel activity

excitatory extracellular ligand-gated ion channel activity

Catalysis of the reaction: pyruvate + (R)-3-amino-2-methylpropanoate = L-alanine + methylmalonate-semialdehyde.

The formation from simpler components of selenocysteine, an essential component of glutathione peroxidase and some other proteins.

inhibitory extracellular ligand-gated ion channel activity

The breakdown into simpler components of selenocysteine, an essential component of glutathione peroxidase and some other proteins.

Catalysis of the reaction: UDP-N-acetyl-D-glucosamine + protein = UDP + 4-N-(N-acetyl-D-glucosaminyl)-protein.

Catalysis of the addition of a galactosyl residue to a non-reducing O-linked N-acetylgalactosamine residue in an O-glycan.

Assembly of gap junctions, which are found in most animal tissues, and serve as direct connections between the cytoplasms of adjacent cells. They provide open channels through the plasma membrane, allowing ions and small molecules (less than approximately a thousand daltons) to diffuse freely between neighboring cells, but preventing the passage of proteins and nucleic acids.

A permanent cessation of all vital functions: the end of life; can be applied to a whole organism or to a part of an organism.

The stepwise addition of sugar residues to the initially added O-linked sugar (usually GalNAc) to form a core O-glycan structure.

The stepwise addition of sugar residues to the initially added O-linked sugar (usually GalNAc) to form the core 1 O-glycan structure, Gal-beta-1-

Catalysis of the reaction: N-sulfo-D-glucosamine + H2O = D-glucosamine + SO4(2-) (sulfate).
