Summary: This gene encodes a member of a family of dynamin-like, integral membrane GTPases. The encoded protein is required for the proper formation of the network of interconnected tubules of the endoplasmic reticulum. Mutations in this gene may be associated with hereditary sensory neuropathy type IF. Alternatively spliced transcript variants that encode distinct isoforms have been described.

ATL3 functions as a receptor for endoplasmic reticulum (ER)-phagy, promoting tubular ER degradation upon starvation. ATL3 specifically binds to GABARAP, but not LC3, subfamily proteins via 2 GABARAP interaction motifs (GIMs). ATL3-GABARAP interaction is essential for ATL3 to function in ER-phagy.

the effects of ATL3 mutations on endoplasmic reticulum network organization go beyond a loss of fusion and shed light on neuropathies caused by atlastin defects.
Title: Sensory-Neuropathy-Causing Mutations in ATL3 Cause Aberrant ER Membrane Tethering.
the mitochondria in these cells display lowered motility, and the number of axonal mitochondria in neurons expressing disease-causing mutations in ATL3 is strongly decreased. These results underscore the functional interdependence of subcellular organelles in health and disease and show that disorders caused by ER-shaping defects are more complex than previously assumed.
Title: Sensory neuropathy-causing mutations in ATL3 affect ER-mitochondria contact sites and impair axonal mitochondrial distribution.
ATL3 Y192C delays endoplasmic reticulum-export by reducing the number of endoplasmic reticulum exit sites, reduces autophagy, fragments the Golgi and causes malformation of the nucleus. In cultured primary neurons, ATL3 Y192C does not localize to the growing axon, resulting in axon growth deficits.

These results suggest that the three ATLs have different capacities to mediate endoplasmic reticulum fusion, with ATL1 being the strongest and ATL3 being the weakest.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
