The directed killing of a target cell by an immune cell.

The catalysis of certain rearrangements of a molecule to break or form a ring.

tyrosine phosphorylation of Stat3 protein

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

Catalysis of the ligation of two substances with concomitant breaking of a diphosphate linkage, usually in a nucleoside triphosphate. Ligase is the systematic name for any enzyme of EC class 6.

ligase activity, forming carbon-oxygen bonds

Catalysis of the ligation of two substances via a carbon-oxygen bond with concomitant breakage of a diphosphate linkage, usually in a nucleoside triphosphate.

ligase activity, forming aminoacyl-tRNA and related compounds

tyrosine phosphorylation of Stat5 protein

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

ligase activity, forming carbon-sulfur bonds

ligase activity, forming carbon-sulphur bonds

Catalysis of the ligation of two substances via a carbon-sulfur bond with concomitant breakage of a diphosphate linkage, usually in a nucleoside triphosphate.

The assembly of DNA, histone proteins, and other associated proteins into chromatin structure, beginning with the formation of the basic unit, the nucleosome, followed by organization of the nucleosomes into higher order structures, ultimately giving rise to a complex organization of specific domains within the nucleus.

Catalysis of the reaction: ATP + dephospho-CoA = ADP + CoA.

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.

ligase activity, forming carbon-nitrogen bonds

Catalysis of the ligation of two substances via a carbon-nitrogen bond with concomitant breakage of a diphosphate linkage, usually in a nucleoside triphosphate.

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.
