The creation of a single organelle from two or more organelles.

The enzymatic modification of the chemical structure of specific sites in rRNA.

The breakdown into simpler components of thymidine, deoxyribosylthymine thymine 2-deoxyriboside, a deoxynucleoside very widely distributed but occurring almost entirely as phosphoric esters in deoxynucleotides and deoxyribonucleic acid, DNA.

The creation of two or more organelles by division of one organelle.

Interacting selectively with an interleukin.

The process whose specific outcome is the progression of the alveolus over time, from its formation to the mature structure. The alveolus is a sac for holding air in the lungs; formed by the terminal dilation of air passageways.

interleukin-1, Type I, activating binding

protein phosphatase type 2A, intrinsic catalyst activity

Catalysis of the reaction: a phosphoprotein + H2O = a protein + phosphate. A protein serine/threonine phosphatase that is polycation-stimulated (PCS), being directly stimulated by protamine, polylysine, or histone H1; it constitutes a subclass of several enzymes activated by different histones and polylysine.

interleukin-1, Type II, blocking binding

The switching of activated B cells from IgM biosynthesis to IgE biosynthesis, accomplished through a recombination process involving an intrachromosomal deletion between switch regions that reside 5' of the IgM and IgE constant region gene segments in the immunoglobulin heavy chain locus.

A protein serine/threonine phosphatase that is polycation-stimulated (PCS), being directly stimulated by protamine, polylysine, or histone H1; it constitutes a subclass of several enzymes activated by different histones and polylysine.

Catalysis of the reaction: S-adenosyl-L-methionine + histone L-lysine = S-adenosyl-L-homocysteine + histone N6-methyl-L-lysine. The methylation of peptidyl-lysine in histones forms N6-methyl-L-lysine, N6,N6-dimethyl-L-lysine and N6,N6,N6-trimethyl-L-lysine derivatives.

The formation from simpler components of CTP, cytidine 5'-triphosphate.
