OSIRIS -
The Osiris gene cluster is present in insects and encodes a family of well conserved putative transmembrane proteins of unknown function. In D. melanogaster, most of the genes are clustered within the uniquely dosage-sensitive Triplo-lethal (Tpl) locus. Flies with either one copy or three copies of Tpl die as late embryos or early first instar larvae. (Adapted from FBrf0173211 and FBrf0217655).

            Additional comments

            The Tpl region is both triplo-lethal and haplo-lethal and neither point nor insertional mutations of Tpl have been isolated despite extensive mutagenesis analysis. This raises the possibility that Tpl consists of a cluster of genes with at least partial redundancy. Osi21 is a member of the "Osiris" family of genes (which contains 23 members). 20 of the "Osiris" genes are located in a cluster within the Tpl region of the genome at 83D-83E (the remaining 3 members - Osi21, Osi22 and Osi23 - are located at three different sites in the genome. None of these 3 loci are triplo-lethal or are located within a haplo-insufficient region). The "Osiris" gene family is also present in the A.gambiae genome and shows remarkable synteny and sequence conservation with the D.melanogaster cluster. There appears to have been selection on the "Osiris" family both for expression level and function. It is suggested that the "Osiris" gene family cluster corresponds to Tpl.

            Origin and Etymology
            Discoverer
            Etymology

            The gene is named "Osiris" since it belongs to a family of related proteins, 20 of which are in a cluster located in the Tpl region, and the "Isis" locus partially rescues the effect of trisomy for this region.
