Vampyrella mitosis

Orthomitosis in Vampyrella occurs late in the cyst stage. Neither microtubule organizing centers (MTOCs) nor centrioles are present during mitosis. While in the trophozoite life stage and early cyst stage, the cell is in interphase. Heterochromatin decrease upon entering the cyst stage as the cell prepares for mitosis. The spherical nuclei increase in size from 1.5-2.0 µm in…

Ectodomain Shedding & Sheddases & a whole bunch of Adams

An ectodomain is the domain of a membrane protein that extends into the extracellular space (the space outside a cell). Ectodomains are usually the parts of proteins that initiate contact with surfaces, which leads to signal transduction. A notable example of an ectodomain is the S protein, commonly known as the spike protein, of the viral particle responsible for the COVID-19 pandemic. The ectodomain region of the…
