Summaries
Gene Group (FlyBase)
CNNM-TYPE Mg2+-EFFLUX TRANSPORTER SUBUNITS -
CNNM-type Mg[2+]-efflux transporters are transmembrane channels allow the passage of cytosolic Mg[2+] ions across the plasma membrane. They possess an intracellular cyclic nucleotide-binding homology (CNBH) domain, which may be involved in regulation by cyclic nucleotides. (Adapted from FBrf0247921.)
Protein Function (UniProtKB)
Probable metal transporter (By similarity). Acts downstream of PRL-1 and protects the nervous system against olfactory carbon dioxide stimulation (PubMed:31404830).
(UniProt, A0A0B7P9G0)
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
uex: unextended
Wings incompletely expanded as in a newly emerged fly, about one-half normal length, and frequently inflated. Tibiae and tarsi of third legs irregularly shortened and gnarled. Posterior scutellars convergent. The rare uex2 - uex7 hemizygous survivors may also have etched tergites and small bodies.
Summary (Interactive Fly)

a functional fly ortholog of the mammalian Cyclin M2 Mg2+-efflux transporter (CNNM) proteins - critical for the memory enhancing property of Mg2+ - Uex function in mushroom body kenyon cells is required for long term memory - functional restoration of uex reveals the MB to be the key site of Mg2+-dependent memory enhancement - Uex acts downstream of PRL-1 - elevated Uex levels in PRL-1 mutants prevent a CO2-induced phenotype - PRL-1 and Uex are required for a wide range of neurons to maintain neuroprotective functions

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.

            Additional comments

            Annotations CG40084 and CR41594 merged as CG42595 in release 5.19 of the genome annotation.

            The 5' UTR of release 3 annotation CG40084 has been split into a separate annotation, CR41594, for release 5.2 of the genome annotation.

            The "l(2)41Ae" locus fails to complement mutations in 7 genes ("l(2)NC37", "l(2)NC38", "l(2)NC133", "l(2)NC110", "l(2)NC70", "l(2)IR3" and "l(2)IR23"). The "l(2)41Ae" locus has previously been shown to have complex complementation behaviour (FBrf0028786). This information suggests that the "l(2)41Ae" "locus" may contain mutations in different genes.

            The six hemizygous late-pupal lethals induced by Hilliker are inferred to be allelic to uex1 on the basis of map position and phenotype.
