Summary: Predicted to enable several functions, including gamma-tubulin binding activity; identical protein binding activity; and transcription coactivator activity. Acts upstream of or within several processes, including centriole replication; cilium assembly; and positive regulation of non-motile cilium assembly. Located in centriole and ciliary basal body. Is expressed in several structures, including brain; foregut; sensory organ; submandibular gland primordium; and tooth. Used to study Seckel syndrome. Human ortholog(s) of this gene implicated in Seckel syndrome 4; primary autosomal recessive microcephaly; and primary autosomal recessive microcephaly 6. Orthologous to human CPAP (centrosome assembly and centriole elongation protein). [provided by Alliance of Genome Resources, Jul 2025]

Cenpj rgulates clia dsassembly and nurogenesis in the developing mouse cortex. Results illustrate that Cenpj regulates cilia disassembly and neurogenesis through Kif2a, indicating that primary cilia dynamics play a crucial role in NPC mitosis and adult neurogenesis.

Data suggest that alcohol/ethanol exposure diminishes pool of proliferative neurons (Neuro2a cell line) through disordering of spindle orientation and promotion of asymmetric cell division; these neuronal abnormalities appear to be due to reduced Cenpj protein expression level.

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.
