Any of the processes involved in the maintenance of an internal equilibrium of water within an organism or cell.

The chemical reactions involving any hormone, naturally occurring substances secreted by specialized cells that affects the metabolism or behavior of other cells possessing functional receptors for the hormone.

The commitment of cells to specific cell fates and their capacity to differentiate into particular kinds of cells. Positional information is established through protein signals that emanate from a localized source within a cell (the initial one-cell zygote) or within a developmental field.

The formation from simpler components of any hormone, naturally occurring substances secreted by specialized cells that affects the metabolism or behavior of other cells possessing functional receptors for the hormone.

major histocompatibility complex class I receptor

A major histocompatibility complex class I receptor. These display processed antigens from the endocytosed bacteria. MHC class I proteins can form complexes with processed antigen peptides only if the antigen is synthesized in the same cell. As a consequence, T lymphocytes can only bind to class-I-positive cells that are synthesizing the antigen (e.g. virus-infected cells).

The breakdown into simpler components of any hormone, naturally occurring substances secreted by specialized cells that affects the metabolism or behavior of other cells possessing functional receptors for the hormone.

The chemical reactions involving progesterone, a steroid hormone produced in the ovary which prepares and maintains the uterus for pregnancy. Also found in plants.

Catalysis of the reaction: ATP + biotin + apo-(propanoyl-CoA:carbon-dioxide ligase (ADP-forming)) = AMP + diphosphate + (propanoyl-CoA:carbon-dioxide ligase (ADP-forming)).

HLA-B specific inhibitory MHC class I receptor activity

A receptor that binds MHC class I molecules of the HLA-B subclass and mediates signaling that inhibits natural killer cell activity.

Catalysis of the reaction: 3-phospho-D-glyceroyl phosphate = 2,3-bisphospho-D-glycerate.
