Combining with vitellogenin to initiate a change in cell activity.

Interacting selectively with ferrous iron, Fe(II).

Interacting selectively with ferric iron, Fe(III).

protein tyrosine phosphatase activator activity

Increases the activity of a phosphatase, an enzyme which catalyzes of the removal of a phosphate group from a tyrosyl phenolic group of a protein.

Catalysis of the transfer of a methyl group to an acceptor molecule.

Catalysis of the transfer of a methyl group to the carbon atom of an acceptor molecule.

Assembly or disassembly of actin filaments by the addition or removal of actin monomers from a filament.

Any process that stops, prevents or reduces the rate, frequency or extent of DNA replication.

Interacting selectively with the enzyme protein phosphatase 1.

Combining with the hedgehog protein to initiate a change in cell activity.

positive transcription elongation factor activity

Any activity that increases the rate of transcription elongation, the addition of ribonucleotides to an RNA molecule following transcription initiation.

A complex that catalyzes the deneddylation of proteins, including the cullin component of SCF ubiquitin E3 ligase; deneddylation increases the activity of cullin family ubiquitin ligases. The signalosome is involved in many regulatory process, including some which control development, in many species; also regulates photomorphogenesis in plants; in many species its subunits are highly similar to those of the proteasome.

Catalysis of the reaction: glycogen + phosphate = maltodextrin + alpha-D-glucose 1-phosphate.

Catalysis of the reaction: ATP + H2O = ADP + phosphate, in the presence of RNA; drives another reaction.

Interacting selectively with any stretch of pyrimidines (cytosine or uracil) in an RNA molecule.

Combining with a neuropeptide to initiate a change in cell activity.

Catalysis of the transfer of a methyl group to the nitrogen atom of an acceptor molecule.

Catalysis of the transfer of a methyl group to the oxygen atom of an acceptor molecule.
