Any process that decreases the stability of an RNA molecule, making it more vulnerable to degradative processes.

A structure lying external to one or more cells, which provides structural support for cells or tissues; may be completely external to the cell (as in animals) or be part of the cell (as in plants).

The addition of an alkyl group to a protein amino acid. An alkyl group is any group derived from an alkane by removal of one hydrogen atom.

Catalysis of the transfer of a xylosyl group to an acceptor molecule, typically another carbohydrate or a lipid.

The chemical reactions involving spermine, a polybasic amine found in human sperm, in ribosomes and in some viruses, which is involved in nucleic acid packaging. Synthesis is regulated by ornithine decarboxylase which plays a key role in control of DNA replication.

The process whose specific outcome is the progression of the pancreas over time, from its formation to the mature structure. The pancreas is an endoderm derived structure that produces precursors of digestive enzymes and blood glucose regulating enzymes.

The chemical reactions involving spermidine, N-(3-aminopropyl)-1,4-diaminobutane.

Interacting selectively with major histocompatibility complex molecules; a set of molecules displayed on cell surfaces that are responsible for lymphocyte recognition and antigen presentation.

Any process that modulates blood pressure.

The process whose specific outcome is the progression of the endocrine pancreas over time, from its formation to the mature structure. The endocrine pancreas is made up of islet cells that produce insulin, glucagon and somatostatin.

Functions to increase the rate of ATP hydrolysis.

major histocompatibility complex class II ligand

Interacting selectively with major histocompatibility complex class I molecules; a set of molecules displayed on cell surfaces that are responsible for lymphocyte recognition and antigen presentation.

The specific activation or halting of processes within a cell so that its vital functions markedly cease, rather than simply deteriorating gradually over time, which culminates in cell death.
