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

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

sensory organ precursor cell fate determination

Process by which a cell becomes capable of differentiating autonomously into a sensory organ precursor cell regardless of its environment; upon determination, the cell fate cannot be reversed.

Enables the directed movement of a nucleoside, a nucleobase linked to either beta-D-ribofuranose (ribonucleoside) or 2-deoxy-beta-D-ribofuranose, (a deoxyribonucleotide), into, out of, within or between cells.

Combining with transforming growth factor beta to initiate a change in cell activity; upon ligand binding, catalyzes the phosphorylation of downstream components of the TGF-beta signaling pathway.

Enables the directed movement of nucleotide-sugars into, out of, within or between cells. A nucleotide-sugars is any nucleotide in which the distal phosphoric residue of a nucleoside 5'-diphosphate is in glycosidic linkage with a monosaccharide or monosaccharide derivative.

Catalysis of the reaction: NAD(P)+ + 17-alpha,20-alpha-dihydroxypregn-4-en-3-one = NAD(P)H + H+ + 17-alpha-hydroxyprogesterone.

Combining with transforming growth factor beta to initiate a change in cell activity; upon ligand binding, catalyzes the phosphorylation of downstream components of the activin signaling pathway.

The dense fibrillar network lying on the inner side of the nuclear membrane.

The directed movement of adenine nucleotides, ATP, ADP, and/or AMP, into, out of, within or between cells.

maintenance of oocyte identity (sensu Insecta)

The process required to ensure that development of the oocyte continues after oocyte specification. Identity is considered to be the aggregate of characteristics by which a structure is recognized. As in, but not restricted to, the true insects (Insecta, ncbi_taxonomy_id:50557).

Formation and development of a dendrite, a freely branching protoplasmic process of a nerve cell.
