CDKL5 Deficiency Disorder (CDD) leads to seizures & intellectual disability. This study shows that #Chlamydomonas CDKL5 kinase is activated by the LF2/CDK20 kinase; CDKL5 in turn regulates #intraflagellar transport via protein abundance & phosphorylation #cilia @plosbiology.org 🧪 plos.io/45490eP
Top: lf5 mutant cells untransformed, or expressing CDKL5-GFP, CDKL5K33R-GFP, CDKL5S162A,T164A,Y166A-GFP, or CDKL5Y166F-GFP, and lf2 mutant cells expressing CDKL5-GFP were stained for flagella (acetylated tubulin, red) and CDKL5 (GFP, green top panels, gray in bottom panels). The cell bodies of all strains are green (or gray) due to autofluorescence. Wild-type CDKL5-GFP concentrates at the basal end of the flagellar shaft (arrows). Note that all of the mutant CDKL5 proteins lack the major enrichment at the basal end of the flagellum but continue to show punctate stain along the flagellar shaft. Scale bar, 5 µm. Z projection of slices taken at 0.5-µm intervals. Bottom: Larger version of the first image in the top row.

How curvature affects epithelial tissues? Answer in 5 papers! To understand this, one must first gain control over curvature. The most logical way of doing this is through scaffolding in vitro — make a shape and attach cells.
