PoptrCAD7, for example, is expressed in leaves and petioles, but presents a very low expression in the bark and xylem.
Acceleration, for example, is expressed as L/T2 in dimensional analysis because it is a distance (L, length) per unit of time (T) squared; whether the actual units of length are expressed in the British Imperial or metric system is immaterial.
For example, is expressed as (5).
In Mayan most relational nouns are metaphorically derived from body parts so that "on top of," for example, is expressed by the word for head.
The monopteros mutant, for example, is expressed in the Arabidopsis embryo, and the mutant is characterized by abnormal divisions in the prospective procambial tissue in the embryo and defective cotyledonary vein formation [10], [11].
Cxcr4, for example, is expressed on the surface of interneurons that migrate into the cortex and appears to be required for normal interneuron positioning from ventral lateral to dorsal medial (69– 73).
In addition, from a disease perspective it is important to know whether a gene involved in a respiratory process, for example, is expressed in the bronchi, the bronchioles or the alveoli, necessitating a high level of granularity in annotation.
FcεR1γ for example, is expressed on the surface of mast cell and cross-linking of these IgE bound receptors leads to mast cell degranulation, cytokine production, prostaglandin synthesis, survival and passive systemic anaphylaxis [ 49].
Cathepsin X (Cat X), for example, is expressed specifically in various cells of the immune system [ 12] and regulates important processes such as proliferation, maturation, migration and adhesion of immune cells, phagocytosis and signal transduction [ 13- 15].
TLR4, for example, is expressed at the surface of myeloid cells but in intracellular compartments in epithelial cells such as A549, BEAS-2B cells, intestinal cells as well as endothelial cells [ 20, 21].
