What's a GeneRIF?
  1. Two intronic variants (rs2241160 and rs2241161) were significantly associated with an increased risk of single-NSAID-induced urticaria/angioedema or anaphylaxis (SNIUAA), suggesting CEP68 to be a key player in both types of Non-steroidal anti-inflammatory drugs hypersensitivity.
    Title: Polymorphisms in CEP68 gene associated with risk of immediate selective reactions to non-steroidal anti-inflammatory drugs.
  2. 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.
  3. It has been proposed that the archetypal linker protein Rootletin maintains centrosome cohesion in part through inhibition of VHL-mediated Cep68 degradation.
    Title: Rootletin prevents Cep68 from VHL-mediated proteasomal degradation to maintain centrosome cohesion.
  4. The Cep68 protein level needs to be fine-tuned in order to ensure that its direct interactors, such as the microcephaly protein Cep215 and PCNT, function properly.
    Title: Centrosomal MCM7 strengthens the Cep68-VHL interaction and excessive MCM7 leads to centrosome splitting resulting from increase in Cep68 ubiquitination and proteasomal degradation.
  5. Cep68 degradation allows Cep215 removal from peripheral pericentriolar material (PCM) preventing centriole separation following disengagement, PCNT cleavage mediates Cep215 removal from core of the PCM to inhibit centriole disengagement and duplication
    Title: Degradation of Cep68 and PCNT cleavage mediate Cep215 removal from the PCM to allow centriole separation, disengagement and licensing.
  6. C-terminal 300-400 amino acids of Cep68 are necessary to localize Cep68 to interphase centrosomes while C-terminal 400-500 amino acids might regulate Cep68 dissociation from centrosomes at mitotic onset.
    Title: Cep68 can be regulated by Nek2 and SCF complex.
  7. CEP68 gene variants may play an important role in MNSAID-UA susceptibility and, despite the different regulatory mechanisms involved depending on the specific affected organ, in the development of hypersensitivity reactions to NSAIDs.
    Title: Variants of CEP68 gene are associated with acute urticaria/angioedema induced by multiple non-steroidal anti-inflammatory drugs.
  8. Centlein complexes with C-Nap1 and Cep68 at the proximal ends of centrioles during interphase.

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.
