Enables the directed movement of oligopeptides into, out of, within or between cells. Oligopeptides are molecules that contain a small number (2 to 20) of amino-acid residues connected by peptide linkages.

aspartic endopeptidase activity, intramembrane cleaving

Catalysis of the hydrolysis of nonterminal peptide linkages in oligopeptides or polypeptides, occurring within the plasma membrane.

tyrosine phosphorylation of Stat3 protein

The process of introducing a phosphoric group to a tyrosine residue of a Stat3 protein.

tyrosine phosphorylation of Stat6 protein

The process of introducing a phosphoric group to a tyrosine residue of a Stat6 protein.

tyrosine phosphorylation of Stat5 protein

The process of introducing a phosphoric group to a tyrosine residue of a Stat5 protein.

tyrosine phosphorylation of Stat1 protein

The process of introducing a phosphoric group to a tyrosine residue of a Stat1 protein.

regulation of tyrosine phosphorylation of STAT protein

Any process that modulates the frequency, rate or extent of the introduction of a phosphoric group to a tyrosine residue of a STAT (Signal Transducer and Activator of Transcription) protein.

pyrimidine nucleotide sugar transporter activity

Enables the directed movement of pyrimidine nucleotide-sugars into, out of, within or between cells. Pyrimidine nucleotide-sugars are pyrimidine nucleotides in glycosidic linkage with a monosaccharide or monosaccharide derivative.

Enables the directed movement of polyols, polyhydric alcohols, into, out of, within or between cells.

Enables the directed movement of glycerol into, out of, within or between cells. Glycerol is 1,2,3-propanetriol, a sweet, hygroscopic, viscous liquid, widely distributed in nature as a constituent of many lipids.

Enables the directed movement of glycerol-3-phosphate into, out of, within or between cells. Glycerol-3-phosphate is a phosphoric monoester of glycerol.

Enables the directed movement of alpha-glucosides into, out of, within or between cells. Alpha-glucosides are glycosides in which the sugar moiety is a glucose residue, and the anomeric carbon of the bond is in an alpha configuration.
