Gene Snapshot
Optic atrophy 1 (Opa1) is a dynamin-related GTPase that mediates fusion of the inner membrane of mitochondria. Opa1 usually works with Marf to coordinately fuse both mitochondrial membranes. Opa1 activity is regulated by proteolytic processing. [Date last reviewed: 2016-09-01]

Additional comments
Renamed from 'opa1-like' to 'Opa1' to reflect preferred usage in the published literature.
One of the introns of opa1-like has the sequence and structural characteristics of a "mirtron"- mirtrons are encoded as an intron of another gene which accumulate as a lariats after splicing and require debranching enzyme for conversion into a functional miRNA. The mirtron encoded by the opa1-like intron is mir-1016.
Other Comments
400bp of dsRNA generated from primer-directed transcription from genomic DNA, corresponding to the gene opa1-like, when transfected into S2 cells results in a majority of cells exhibiting a highly fragmented mitochondrial network.
Mutants fail to pupariate but survive as third instar until 8-10 days after egg laying.
dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
