Interacting selectively with a G-protein-coupled receptor.

Catalysis of the reaction: CMP-N-acetylneuraminate + glycano-1,3-(N-acetyl-alpha-D-galactosaminyl)-glycoprotein = CMP + glycano-(2,6-alpha-N-acetylneuraminyl)-(N-acetyl-D-galactosaminyl)-glycoprotein.

A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating lowered oxygen tension.

Cell migration that is accomplished by extension and retraction of a pseudopodium.

Catalysis of the reaction: phosphatidylinositol-4,5-bisphosphate + H2O = phosphatidyl inositol-4-phosphate + phosphate.

A structure in the head of a spermatozoon that contains acid hydrolases, and is concerned with the breakdown of the outer membrane of the ovum during fertilization. It lies just beneath the plama membrane and is derived from the lysosome.

A structure found most metazoan nucleoli, but not usually found in lower eukaryotes; surrounded by the dense fibrillar component; the zone of transcription from multiple copies of the pre-rRNA genes is in the border region between these two structures.

Catalysis of the reaction: glucose(out) + Na+(out) = glucose(in) + Na+(in).

A structure found in the nucleolus, which contains newly synthesized preribosomal RNA (pre-rRNA) and a collection of proteins.

Enables the directed movement of maltose into, out of, within or between cells. Maltose is the disaccharide 4-O-alpha-D-glucopyranosyl-D-glucopyranose, an intermediate in the enzymatic breakdown of glycogen and starch.

A structure found in the nucleolus, which contains nearly completed preribosomal particles destined for the cytoplasm.

Catalysis of the reaction: maltose(out) + H+(out) = maltose(in) + H+(in).

Combining with an extracellular or intracellular peptide to initiate a change in cell activity.

Enables the directed movement of myo-inositol into, out of, within or between cells. Myo-inositol is 1,2,3,4,5/4,6-cyclohexanehexol, a growth factor for animals and microorganisms.
