Catalysis of the reaction: nucleoside triphosphate + RNA (n) = diphosphate + RNA (n+1); uses an RNA template.

Interacting selectively with low-density lipoprotein, one of the classes of lipoproteins found in blood plasma in many animals (data normally relate to humans).

tyrosine phosphorylation of STAT protein

The process of introducing a phosphoric group to a tyrosine residue of a STAT (Signal Transducer and Activator of Transcription) protein.

protein import into mitochondrial matrix

The import of proteins across the outer and inner mitochondrial membranes into the matrix. Unfolded proteins enter the mitochondrial matrix with a chaperone protein; the information required to target the precursor protein from the cytosol to the mitochondrial matrix is contained within its N-terminal matrix-targeting sequence. Translocation of precursors to the matrix occurs at the rare sites where the outer and inner membranes are close together.

Catalysis of the reaction: NAD+ + (ADP-D-ribosyl)(n)-acceptor = nicotinamide + (ADP-D-ribosyl)(n+1)-acceptor.

Interacting selectively with molybdenum (Mo) ions.

Catalysis of the reaction: ATP + NAD+ = ADP + NADP+.

The transport of dimerized STAT (Signal Transducers and Activators of Transcription) proteins into the nucleus following activation by members of the janus activated kinase (JAK) family of tyrosine kinases.

Catalysis of the reaction: ATP + deamido-NAD+ + L-glutamine + H2O = AMP + diphosphate + NAD+ + L-glutamate.

nitric oxide mediated signal transduction

A series of molecular signals mediated by the detection of nitric oxide (NO).

Catalysis of the reaction: NAD+ + H2O = nicotinamide + ADP-ribose.

small GTPase mediated signal transduction

Any series of molecular signals in which a small monomeric GTPase relays one or more of the signals.

The process whereby relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate.
