Any process that modulates the frequency, rate or extent of the directed movement of a motile cell or organism towards a higher concentration in a concentration gradient of a specific chemical.

Any process that stops, prevents, or reduces the frequency, rate or extent of the directed movement of a motile cell or organism towards a higher concentration in a concentration gradient of a specific chemical.

Any process that initiates the directed movement of a motile cell or organism towards a lower concentration in a concentration gradient of a specific chemical.

Any process that activates or increases the frequency, rate or extent of the directed movement of a motile cell or organism towards a lower concentration in a concentration gradient of a specific chemical.

Any process that initiates the directed movement of a motile cell or organism towards a higher concentration in a concentration gradient of a specific chemical.

The process in which a relatively unspecialized cell acquires the specialized features of an early stripe melanocyte (ESM). In zebrafish, ESMs develop during the first phase (2-3 weeks of development) of the larva to adult transition (2-4 weeks of development).

The process in which a relatively unspecialized cell acquires specialized features of a melanocyte.

The process in which a relatively unspecialized cell acquires the specialized features of a late stripe melanocyte (LSM). In zebrafish, LSMs develop during the second phase (3-4 weeks of development) of the larva-to-adult transition (2-4 weeks of development).

The process in which a relatively unspecialized cell acquires the specialized features of an iridophore. Iridophores are pigment cells derived from the neural crest. They contain guanidine or other purine crystals deposited in stacks called reflecting platets or iridisomes. This gives them a silver, gold, or iridescent appearance.

The process in which a relatively unspecialized cell acquires the specialized features of a xanthophore cell. Xanthophores are pigment cells derived from the neural crest. They contain pteridine and/or carotenoid pigments in structures called pterinosomes or xanthosomes. This makes them yellow to orange in appearance.

OBSOLETE. Catalysis of the reactions: ATP + 1D-myo-inositol 1,3,4-trisphosphate = ADP + 1D-myo-inositol 1,3,4,5-tetrakisphosphate, and ATP + 1D-myo-inositol 1,3,4-trisphosphate = ADP + 1D-myo-inositol 1,3,4,6-tetrakisphosphate.

A multiprotein complex that binds microtubules in a Hedgehog-dependent manner, and is required for signal transduction by members of the Hedgehog family of proteins. The core components of the complex are the serine/threonine protein kinase Fused, the kinesin motor protein Costal2 (Cos2), and a zinc finger transcription factor (Gli family members in humans, and Cubitus interruptus (Ci) in Drosophila).

Catalysis of the hydroxylation of an ecdysteroid at carbon position 25. Ecdysteroids are a group of polyhydroxylated ketosteroids which initiate post-embryonic development, particularly metamorphosis, in insects and other arthropods.

Any process pertaining to the functions of the nervous and muscular systems of an organism.

The regionalization process that subdivides the wing imaginal disc into the wing and notum (body wall) subfields, thus determining whether cells ultimately differentiate wing or notum-specific structures.

The series of events involved in visual perception in which a light stimulus is received and converted into a molecular signal.

Transient adhesive interactions between leukocytes and endothelial cells lining blood vessels. Carbohydrates on circulating leukocytes bind selectins on the vessel wall causing the leukocytes to slow down and roll along the inner surface of the vessel wall. During this rolling motion, transitory bonds are formed and broken between selectins and their ligands. Typically the first step in cellular extravasation (the movement of leukocytes out of the circulatory system, towards the site of tissue damage or infection).

The attachment of a leukocyte to vascular endothelial cell via adhesion molecules.
