Fusion Pores as Regulators of Quantal Size and Cellular Physiology
BioEssays, Volume 47, Issue 11, November 2025.During regulated exocytosis, membrane fusion regulatory factors act directly on SNAREs and membrane lipids to control fusion pore dynamics. This, in turn, leads to a differential amount of cargo release (referred to in this article as “quantal size”) across various cell types, thereby triggering distinct physiological cues.

Tandemly repeated C-C-C-C-A-A hexanucleotide of Tetrahymena rDNA is present elsewhere in the genome and may be related to the alteration of the somatic genome. [PDF]
, 1981 The ribosomal RNA genes of the Tetrahymena macronucleus exist as extrachromosomal, linear molecules. The termini of these molecules have been shown to contain the tandemly repeated hexanucleotide (C-C-C-C-A-A)n.

Influence of cellular shape on sliding behavior of ciliates
Communicative & Integrative Biology, 2018 Some types of ciliates accumulate on solid/fluid interfaces. This behavior is advantageous to survival in nature due to the presence of sufficient nutrition and stable environments.
