The process by which a cell in a multicellular organism interprets its surroundings.

The process by which a neuronal cell in a multicellular organism interprets its surroundings.

Part of the plasma membrane at the basal end of the cell. Often used in reference to animal polarized epithelial membranes, where the basal membrane is the part attached to the extracellular matrix, or in plant cells, where the basal membrane is defined with respect to the zygotic axis.

Any collagen polymer associated with collagen fibrils and in which the collagen monomers contain two or more relatively short triple-helical domains connected by non-triple-helical sequences; the acronym FACIT stands for fibril-associated collagen with interrupted triple helix.

Catalysis of the reaction: RS-CH2-CH(NH3+)COO- = RSH + NH3 + pyruvate.

A collagen heterotrimer containing type IX alpha chains in alpha1(IX)alpha2(IX)alpha3(IX) trimers; type IX collagen triple helices associate to form a structure that links glycosaminoglycans to type II collagen fibrils.

The process whereby a relatively unspecialized cell acquires specialized features of an epidermal cell, any of the cells making up the epidermis.

The modification of peptidyl-glutamic acid.

Interacting selectively with neurexins, synaptic cell surface proteins related to latrotoxin receptor, laminin and agrin. Neurexins act as cell recognition molecules at nerve terminals.

The directed movement of substances that are in liquid form in normal living conditions into, out of, within or between cells.

Stops, prevents or reduces the activity of any enzyme that catalyzes the hydrolysis of ATP to ADP and orthophosphate.

The establishment, maintenance and elaboration of the anterior/posterior axis.

The formation from simpler components of chemokines, any of a subgroup of cytokines which act primarily on hemopoietic cells in acute and inflammatory processes and other immunoregulatory functions.

Any process that modulates the frequency, rate or extent of the formation from simpler components of cytokines.
