Interacting selectively with monomeric or multimeric forms of actin, including actin filaments.

Enables the directed movement of UDP-N-acetylglucosamine into, out of, within or between cells. N-acetylglucosamine is a substance composed of N-acetylglucosamine, a common structural unit of oligosaccharides, in glycosidic linkage with uridine diphosphate.

Catalysis of the reaction: CDP-choline + N-acylsphingosine = CMP + sphingomyelin.

Enables the directed movement of N-acetylgalactosamine into, out of, within or between cells. N-acetylgalactosamine is a substance composed of N-acetylgalactosamine, a common structural unit of oligosaccharides, in glycosidic linkage with uridine diphosphate.

Catalysis of the reaction: phosphatidylcholine + H2O = 1-acylglycerophosphocholine + a carboxylate; requires Ca2+.

Catalysis of the reaction: deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1). Catalyzes extension of the 3'- end of a DNA strand by one deoxynucleotide at a time using an internal RNA template that encodes the telomeric repeat sequence.

Catalysis of the reaction: phosphatidylcholine + H2O = 1-acylglycerophosphocholine + a carboxylate; does not require Ca2+.

telomeric template RNA reverse transcriptase activity

Catalysis of the extension of the 3' end of a DNA strand by one deoxynucleotide at a time. Cannot initiate a chain de novo; uses the RNA subunit of the telomerase enzyme complex as its template.

Interacting selectively with an RNA molecule or a portion thereof.

Catalysis of the unwinding of an RNA helix.

Interacting selectively with double-stranded RNA.

double-stranded RNA adenosine deaminase activity

Interacting selectively with single-stranded RNA.

The chemical reactions involving cyclic GMP, guanosine 3',5'-phosphate.

The directed movement of copper (Cu) ions within a cell.

Addition of multiple ubiquitin moieties to a protein, forming a ubiquitin chain.

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

Interacting selectively with pre-messenger RNA (pre-mRNA) or messenger RNA (mRNA).
