The specification of the anterior/posterior axis of the embryo by products of genes expressed in the zygote; exemplified in insects by the gap genes, pair rule genes and segment polarity gene cascade.

The specification of the anterior/posterior axis of the embryo by products of genes expressed in the zygote; exemplified in insects by the gap genes, pair rule genes and segment polarity gene cascade.

The establishment of an organism's body plan or part of an organism with respect to the left and right halves. The pattern can either be symmetric, such that the halves are mirror images, or asymmetric where the pattern deviates from this symmetry.

The chemical reactions and pathways involving glycoproteins, any protein that contains covalently bound glycose (i.e. monosaccharide) residues; the glycose occurs most commonly as oligosaccharide or fairly small polysaccharide but occasionally as monosaccharide.

Any protein maturation process achieved by the cleavage of a peptide bond or bonds within a protein. Protein maturation is the process leading to the attainment of the full functional capacity of a protein.

Any protein maturation process achieved by the cleavage of a peptide bond or bonds within a protein. Protein maturation is the process leading to the attainment of the full functional capacity of a protein.

The generation of a mature peptide hormone by posttranslational processing of a prohormone.

The appearance of nerve growth factor (NGF) due to biosynthesis or secretion by cells in a neuron's target field, resulting in an increase in its intracellular or extracellular levels.

The controlled release of a substance by a cell.

The generation of a mature peptide hormone by posttranslational processing of a prohormone.

Any process that modulates the frequency, rate or extent of the activity of any BMP receptor signaling pathway.

The generation of a mature nerve growth factor (NGF) by proteolysis of a precursor.

The appearance of nerve growth factor (NGF) due to biosynthesis or secretion by cells in a neuron's target field, resulting in an increase in its intracellular or extracellular levels.

The controlled release of a substance by a cell.

Any process that modulates the activity of the enzyme lipoprotein lipase.

A type of programmed cell death that occurs in the epidermis, morphologically and biochemically distinct from apoptosis. It leads to the formation of corneocytes, i.e. dead keratinocytes containing an amalgam of specific proteins (e.g., keratin, loricrin, SPR and involucrin) and lipids (e.g., fatty acids and ceramides), which are necessary for the function of the cornified skin layer (mechanical resistance, elasticity, water repellence and structural stability).

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

The external part of the cell wall and/or plasma membrane.

An extracellular matrix consisting mainly of proteins (especially collagen) and glycosaminoglycans (mostly as proteoglycans) that provides not only essential physical scaffolding for the cellular constituents but can also initiate crucial biochemical and biomechanical cues required for tissue morphogenesis, differentiation and homeostasis. The components are secreted by cells in the vicinity and form a sheet underlying or overlying cells such as endothelial and epithelial cells.

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

The volume enclosed by the membranes of any cisterna or subcompartment of the Golgi apparatus, including the cis- and trans-Golgi networks.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The external part of the cell wall and/or plasma membrane.
