lat, latheo, ORC, l(2)49Fd, vr6
ORC3 homolog - regulates DNA replication - also, a presynaptic protein with a role in the Ca2+-dependent synaptic modulation mechanisms necessary for behavioral plasticity

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

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).
lat message is detected in the adult brain.

Please Note FlyBase no longer curates genomic clone accessions so this list may not be complete
Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see JBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
polyclonal
The lat gene product functions in DNA replication during cell proliferation.
Cessation of cell proliferation in third instar larvae defines the phenotypic defect of null mutations in the lat gene.
The lat gene product is specifically localised to the synaptic boutons.
The lat gene product plays a central role in regulating Ca2+- and activity-dependent synaptic plasticity.
Basal synaptic transmission amplitude at the lat mutant NMJ is elevated 3 to 4 fold, and Ca2+ dependence of transmission is significantly reduced. Multiple forms of synaptic facilitation and posttetanic potentiation are strongly depressed or absent at the mutant synapse.
Genetic dissection of the learning and memory gene lat.
lat is involved in the middle term component of memory formation (MTM).
Source for identity of: Orc3 lat
Renamed from 'lat' to 'Orc3' to be consistent with the nomenclature for the other 5 genes encoding subunits of the 'origin recognition complex' in D. melanogaster and the established nomenclature for these conserved genes across species. 'lat'/'latheo' are retained as synonyms for the gene.
'latheo' is Greek for "to cause a person not to know".
Named after a Greek word, meaning "forgetful", related to the name of one of the rivers of Hades, Lethe, whose waters caused all those who drank from them to forget their former life.
"latheo" is Greek: "to cause a person not to know" (Benet's Reader's Encyclopedia 1987).
