The process in which a relatively unspecialized cell acquires specialized features of an amacrine cell, an interneuron generated in the inner nuclear layer (INL) of the vertebrate retina. Amacrine cells integrate, modulate, and interpose a temporal domain in the visual message presented to the retinal ganglion cells, with which they synapse in the inner plexiform layer. Amacrine cells lack large axons.

The rhythmic process of defecation that consists of an intestinal oscillator which regulates calcium waves. These waves in turn control a stereotypical, three-part pattern of muscle contractions. In some organisms, defecation can recur with a regularity more frequent than every 24 hours. For example, in a well-fed Caenorhabditis elegans, the defecation motor program occurs approximately every 45 seconds, and is temperature- and touch-compensated.

The specific actions or reactions of an organism that recur with a regularity more frequent than every 24 hours.

The process in which a relatively unspecialized cell acquires specialized features of a smooth muscle cell surrounding the aorta.

The process in which a relatively unspecialized endothelial cell acquires specialized features of a venous endothelial cell, a thin flattened cell that lines the inside surfaces of veins.

Catalysis of the reaction: isoguanine + H2O = xanthine + NH3.

The commitment of a cell to an arterial endothelial cell fate and its capacity to differentiate into an arterial endothelial cell.

The commitment of a cell to a blood vessel endothelial cell fate and its capacity to differentiate into a blood vessel endothelial cell.

Catalysis of the hydrolysis of terminal 1,4-beta-linkages of N-acetyl-D-glucosamine (GlcNAc) polymers of chitin and chitodextrins. Typically, exochitinases progressively cleave off two subunits from the reducing or non-reducing ends of the chitin chain.

The progression of the venous blood vessel over time from its initial formation to the mature structure. Venous blood vessels carry blood back to the heart after the capillary bed.

The process in which a relatively unspecialized cell acquires specialized features of a smooth muscle cell; smooth muscle lacks transverse striations in its constituent fibers and are almost always involuntary.

The process in which a relatively unspecialized endothelial cell acquires specialized features of an arterial endothelial cell, a thin flattened cell that lines the inside surfaces of arteries.

OBSOLETE. Enables the directed movement of MAPK phosphatase into, out of or within a cell, or between cells.

A process involved in cell fate commitment of an endothelial cell. Once determination has taken place, a cell becomes committed to differentiate down a particular pathway regardless of its environment.

The directed movement of a MAPK phosphatase from the nucleus to the cytoplasm.

The directed movement of a protein from the nucleus into the cytoplasm.

The commitment of a cell to a venous endothelial cell fate and its capacity to differentiate into an venous endothelial cell.

Leptomycin B-sensitive movement of a MAPK phosphatase from the nucleus to the cytoplasm.

The process, occurring in the embryo, by which the anatomical structures of a nail plate are generated and organized. The nail plate is the hard and translucent portion of the nail, composed of keratin, and serves to protect the tips of digits.
