Rootletin forms large, diffusionally stable bifurcating fibers, which amass slowly on mature centrioles over many hours from anaphase. Nascent centrioles (procentrioles), in contrast, do not form roots and must be licensed to do so through PLK1 activity.
Title: Stable centrosomal roots disentangle to allow interphase centriole independence.
CEP68 is important in forming rootletin filaments that branch off centrioles and to modulate the thickness of rootletin fibers.
Title: STED nanoscopy of the centrosome linker reveals a CEP68-organized, periodic rootletin network anchored to a C-Nap1 ring at centrioles.
It has been proposed that the archetypal linker protein Rootletin maintains centrosome cohesion in part through inhibition of VHL-mediated Cep68 degradation.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
