  • data suggest centrosomal functions for C10orf90 and KIAA1731 and new centriole-related functions for ALMS1. (PMID:20844083)
  • A newborn centriole-enriched protein, KIAA1731/CEP295, specifically mediates centriole-to-centrosome conversion but dispensable for cartwheel removal. (PMID:25131205)
  • our results indicate that CEP295 directly interacts with microtubules, and that excess CEP295 could induce the assembly of overly long centrioles. Furthermore, exogenous expression of the N-terminal domain of CEP295 exerts a dominant-negative effect on centriole elongation. Collectively, these findings suggest that CEP295 is essential for building the distal half centrioles and for post-translational modification of centr (PMID:27185865)
  • Study shows that the interaction between Cep295 and Cep192 seems to be crucial for the integrity of centriole structure and also for daughter-to-mother centriole conversion. (PMID:27562453)

Function. Centriole-enriched microtubule-binding protein involved in centriole biogenesis. Essential for the generation of the distal portion of new-born centrioles in a CPAP- and CEP120-mediated elongation dependent manner during the cell cycle S/G2 phase after formation of the initiating cartwheel structure. Required for the recruitment of centriolar proteins, such as POC1B, POC5 and CEP135, into the distal portion of centrioles. Also required for centriole-to-centrosome conversion during mitotic progression, but is dispensable for cartwheel removal or centriole disengagement. Binds to and stabilizes centriolar microtubule. May be involved in ciliogenesis.

Subunit / interactions. Interacts (via ALMS motif) with microtubules; this interaction is direct.

Subcellular location. Cytoplasm. Cytoskeleton. Microtubule organizing center. Centrosome. Centriole. Spindle.

Disease relevance. Seckel syndrome 11 (SCKL11) [MIM:620767] A form of Seckel syndrome, a rare autosomal recessive disorder characterized by proportionate dwarfism of prenatal onset associated with low birth weight, growth retardation, severe microcephaly with a bird-headed like appearance, and intellectual disability. The disease is caused by variants affecting the gene represented in this entry.

Domain organisation. The N-terminal and the ALMS motif-containing C-terminal regions are essential for CEP295-mediated centriole elongation.
