Summary: Predicted to enable alpha-tubulin binding activity. Involved in flagellated sperm motility. Located in axoneme and neuronal cell body. Is active in axonemal A tubule inner sheath and sperm flagellum. Is expressed in several structures, including brain; epithelium; future hindbrain roof plate; spinal cord ventricular layer; and spleen. Used to study juvenile myoclonic epilepsy.

Epilepsy protein Efhc1/myoclonin1 is expressed in cells with motile cilia but not in neurons or mitotic apparatuses in brain.
Title: Epilepsy protein Efhc1/myoclonin1 is expressed in cells with motile cilia but not in neurons or mitotic apparatuses in brain.
We reviewed whether variants damage EFHC1 functions, whether efhc1(-/-) KO mice recapitulate CTC convulsions and "microdysgenesis" neuropathology, and whether supernumerary synaptic and dendritic phenotypes can be rescued in the fly model when EFHC1 is overexpressed
Title: EFHC1 variants in juvenile myoclonic epilepsy: reanalysis according to NHGRI and ACMG guidelines for assigning disease causality.
Efhc1 (-/-) mouse did not show any abnormalities such as disruption of mitotic spindle structure, impaired M-phase progression, and an increase of apoptosis. Further investigations are required to clarify these discrepancies.
Title: Re-evaluation of myoclonin1 immunosignals in neuron, mitotic spindle, and midbody--nonspecific?
The juvenile myoclonic epilepsy-related protein EFHC1 interacts with the redox-sensitive TRPM2 channel linked to cell death.
Title: The juvenile myoclonic epilepsy-related protein EFHC1 interacts with the redox-sensitive TRPM2 channel linked to cell death.
In the adult, low mRNA expression was detected in several brain structures such as cortex, striatum, hippocampus and cerebellum. At E16, EFHC1 mRNA was shown to be expressed in all layers of cortex and not only in cells lining ventricles.
Title: Distribution of EFHC1 or Myoclonin 1 in mouse neural structures.
Data report the expression profile and distribution of Efhc1 messenger RNA during mouse and rat brain development, and suggest that Efhc1 expression is more important during initial phases of brain development.
Title: Expression profile and distribution of Efhc1 gene transcript during rodent brain development.
Decrease or loss of function of myoclonin1 may be the molecular basis for epilepsies caused by EFHC1 mutations.
Title: Efhc1 deficiency causes spontaneous myoclonus and increased seizure susceptibility.
Efhc1 is most abundantly expressed in tissues rich in highly ciliated cells, such as olfactory sensory neurons, and is predicted to be important to cilia.
Title: Tissue expression patterns identify mouse cilia genes.
abundantly present in sperm flagella and tracheal cilia but only in a small amount in the brain
Title: The mouse ortholog of EFHC1 implicated in juvenile myoclonic epilepsy is an axonemal protein widely conserved among organisms with motile cilia and flagella.

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.
