Gene Group (FlyBase)
SODIUM CHANNEL-LIKE CATION CHANNEL SUBUNITS -
The sodium-channel like cation channels are a family of ion channel proteins that contain a DEEA ion-selectivity pore motif. They have been found in a variety of invertebrate species. This family conducts several cations in a voltage-gated manner. (Adapted from FBrf0221058).
Protein Function (UniProtKB)
Mediates the voltage-dependent sodium ion permeability of excitable membranes. Plays a role in processing of olfactory information during the olfactory avoidance response.

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Domain

The sequence contains 4 internal repeats, each with 5 hydrophobic segments (S1, S2, S3, S5, S6) and one positively charged segment (S4). Segments S4 are probably the voltage-sensors and are characterized by a series of positively charged amino acids at every third position.

        Isolated from a D.melanogaster genomic library using a probe corresponding to the transmembrane segment IVS6 of the eel sodium channel gene.

        NaCP60E has been cloned and sequenced.

        Identification: Isolated from a genomic library, using an eel sodium channel cDNA fragment as a probe.

        Structural gene for sodium-channel protein.

        Additional comments

        Annotations CG9071 and CG18506 merged as CG34405 in release 5.2 of the genome annotation.

        The P{lArB}NaCP60Esmi60E insertion (which results in a smell-impaired phenotype) maps within an intron of NaCP60E and is also near the promoter region of RpL41 (which is nested within the second intron of NaCP60E). Evidence indicates that the smell-impaired phenotype caused by the P{lArB}NaCP60Esmi60E insertion is due to an effect on NaCP60E and not RpL41; a revertant of NaCP60Esmi60E showing wild-type olfactory behaviour (NaCP60Esmi60E-rev16) shows full restoration of NaCP60E transcript expression and a massive reduction in RpL41 transcription.

        "NaCP60E" is a candidate gene for "smi60E".
