Dual localization of receptor-type adenylate cyclases and cAMP response protein 3 unveils the presence of two putative signaling microdomains in Trypanosoma cruzi

open access: yesmBio, 2023
Trypanosoma cruzi is the etiologic agent of Chagas disease, a leading cause of disability and premature death in the Americas. This parasite spends its life between a triatomine insect and a mammalian host, transitioning between developmental stages in ...

Copine A regulates the size and exocytosis of contractile vacuoles and postlysosomes in Dictyostelium

open access: yesFEBS Open Bio, 2020
Copines are a family of cytosolic proteins that associate with membranes in a calcium‐dependent manner and are found in many eukaryotic organisms. Dictyostelium discoideum has six copine genes (cpnA‐cpnF), and cells lacking cpnA(cpnA−) have defects in ...

An organelle K⁺ channel is required for osmoregulation in Chlamydomonas reinhardtii [PDF]

open access: yes, 2016
Fresh water protozoa and algae face hypotonic challenges in their living environment. Many of them employ a contractile vacuole system to uptake excessive water from the cytoplasm and expel it to the environment to achieve cellular homeostasis.
