Sequence and structural alignments reveal insights into ANKLE2 evolution and function

open access: yesProtein Science, Volume 35, Issue 6, June 2026.
Abstract ANKLE2 is an enigmatic protein with emerging roles in cell division, development, and virus replication. While ANKLE2 orthologs are present in all animals, its domain composition has evolved over time. ANKLE2's two namesake domains, the ankyrin repeat and LEM domains (named for LAP2, Emerin, and MAN1), have clear and defined roles; however ...

The evolution of cognitive abilities in marine animals: a hypothesis based on insights about cognition gene polymorphisms in Coelocanths and lungfish

open access: yesAcademia Molecular Biology and Genomics
Both coelacanths and lungfish have fossil evidence dating back 400 million years, placing them at a critical evolutionary juncture when marine animals transitioned to terrestrial environments. An intriguing question lies in the extent to which

Discovery of J chain in African lungfish (Protopterus dolloi, Sarcopterygii) using high throughput transcriptome sequencing: implications in mucosal immunity. [PDF]

open access: yesPLoS ONE, 2013
J chain is a small polypeptide responsible for immunoglobulin (Ig) polymerization and transport of Igs across mucosal surfaces in higher vertebrates. We identified a J chain in dipnoid fish, the African lungfish (Protopterus dolloi) by high throughput ...

The subunit composition of the mammalian Mediator complex is not conserved in all vertebrates: Insights from evolutionary plasticity of fish genomes

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract The Mediator complex is an indispensable, multi‐subunit protein transcriptional coactivator with a central role in gene expression in Eukaryotes. Among vertebrates, its molecular structure and subunit composition are well‐known only for mammals.

Eimeria lepidosirenis n.sp. (Apicomplexa:Eimeriidae) of the South American lungfish Lepidosiren paradoxa (Osteichthyes:Dipnoi) from Amazonian Brazil

open access: yesMemorias do Instituto Oswaldo Cruz, 2006
The mature oocysts of Eimeria lepidosirenis n.sp. are described in faeces removed from the lower region of the intestine of a single specimen of the South American lungfish Lepidosiren paradoxa, from Belém, state of Pará, Amazonian Brazil.

Ethmosphenoid endocasts elucidate evolutionary brain divergences and interrelationships of stem tetrapods (Sarcopterygii, Tetrapodomorpha)

open access: yesPapers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Nearly half of all living vertebrate diversity can be traced back to a single lineage of lobe‐finned fishes (piscine sarcopterygians) that radiated during the Palaeozoic Era. In recent years, the phylogenetic framework of tetrapodomorph fishes has largely stabilized, with the exception of the ‘Osteolepiformes’, the interrelationships of which ...

High resolution transmission electron microscopy of developing enamel in the Australian lungfish, Neoceratodus forsteri (Osteichthyes:Dipnoi)

open access: yes, 2007
The permanent tooth plates of the Australian lungfish, Neoceratodus forsteri, are covered by enamel that develops initially in a similar manner to that of other vertebrates. As the enamel layer matures, it acquires several unusual characteristics. It has

From Infestation to Recovery: Evaluating Changes in Livelihoods and Fishing Productivity Following the Biocontrol of Kariba Weed Along Kyoga Basin Lakes and Kibimba Dam

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT The invasive kariba weed (Salvinia molesta) has severely degraded aquatic ecosystems in Uganda's Kyoga basin lakes and Kibimba Dam, disrupting fisheries, navigation and community livelihoods. Between 2017 and 2021, the National Agricultural Research Organisation implemented a biological control program using the host‐specific weevil ...
