AMP-deaminase (AMPD, EC 3.5.4.6), which catalyzes the irreversible hydrolytic deamination of AMP to IMP and ammonia, is an important energy-related enzyme. The partial genomic sequence of the gene encoding myoadenylate deaminase (AMPD1) from the teleost fish Platichthys flesus was determined. The amino acid sequence of P. flesus AMPD1 shows 82% homology with that of the teleost fish Danio rerio. Comparison of genomic sequences of P. flesus and Rattus norvegicus reveals a high degree of conservation of both sequence and structural organization. A phylogenetic analysis of AMPD sequences shows that bony fish and mammalian AMPD1s arise by duplication of a common primordial gene.

Osmoregulation is essential for the survival of aquatic organisms, particularly teleost fish facing osmotic challenges in environments characterized by variable salinity. While the gills are known for ion exchange, the intestine's role in water and salt absorption is gaining attention. Here, we investigated the adaptive responses of the intestine to salinity stress in guppies (), observing significant morphological and transcriptomic alterations.

Tumor necrosis factor receptor-associated factors (TRAFs) act as signal transducers and are critical in many biological processes. However, in contrast to mammals, the function of TRAFs in teleost is still largely unknown. In this study, we identified and cloned eight TRAF genes in snakehead (Channa argus), namely CaTRAF2aa, CaTRAF2ab, CaTRAF2b, CaTRAF3, CaTRAF4a, CaTRAF5, CaTRAF6, and CaTRAF7.

Identifying new organisms that allow linking brain-wide circuit dynamics to complex adaptive behaviors is an ongoing challenge. A new study has demonstrated that Danionella cerebrum - a miniature teleost fish - is capable of multimodal sensory discrimination and displays oxytocin-dependent social interaction, thus opening the way for a wide range of detailed circuit investigations.

In the wild, stressors occur with varying likelihood throughout the day, leading animals to evolve plastic stress responses that exhibit circadian rhythmicity. In mammals, studies have revealed that the circadian plasticity of stress response may differ with age. However, such developmental effects have been largely overlooked in other vertebrate groups.
