What's a GeneRIF?

the Insert B domain of the Dnm1 guanosine triphosphatase (a DRP) contains a novel motif required for association with the mitochondrial adaptor Mdv1
Title: A novel motif in the yeast mitochondrial dynamin Dnm1 is essential for adaptor binding and membrane recruitment.
in addition to dimerization, the unusually long Mdv1 coiled coil serves a scaffolding function to stabilize the Mdv1-Fis1 complex.
Title: Crystal structure of mitochondrial fission complex reveals scaffolding function for mitochondrial division 1 (Mdv1) coiled coil.
Although deletion of Ty3 spacer domain dramatically reduced retrotransposition, significant Gag3 processing and cDNA synthesis occurred.
Title: The TY3 Gag3 spacer controls intracellular condensation and uncoating.
Mdv1 CC lies parallel to the bilayer with N termini at opposite ends bound to Fis1 and C-terminal beta-propeller domains (Dnm1-binding sites) extending into the cytoplasm
Title: Molecular architecture of a dynamin adaptor: implications for assembly of mitochondrial fission complexes.
Mdv1 played a postmitochondrial targeting role in division by interacting & coassembling with the GTP-bound form of Dnm1; this regulated interaction nucleated & promoted self-assembly of Dnm1 into helical structures which drive membrane scission
Title: Mechanistic analysis of a dynamin effector.
findings show that Dnm1p-dependent peroxisome fission requires Fis1p, Caf4p and Mdv1p; association of Caf4p and Mdv1p with peroxisomes relies on Fis1p
Title: Dnm1p-dependent peroxisome fission requires Caf4p, Mdv1p and Fis1p.
the concave surface of the Fis1 tetratricopeptide repeat-like domain is evolutionarily conserved to bind the dynamin-like GTPase Dnm1 and not Mdv1 as previously predicted
Title: Direct binding of the dynamin-like GTPase, Dnm1, to mitochondrial dynamics protein Fis1 is negatively regulated by the Fis1 N-terminal arm.
Dnm1p dimers are initially recruited to the membrane via interaction with Mdv1p.Fis1p complexes
Title: Dimeric Dnm1-G385D interacts with Mdv1 on mitochondria and can be stimulated to assemble into fission complexes containing Mdv1 and Fis1.
the N terminus of Fis1 is a prerequisite to recruit Mdv1 to facilitate mitochondrial fission
Title: Novel structure of the N terminus in yeast Fis1 correlates with a specialized function in mitochondrial fission.
dynamic interactions between Mdv1 and Dnm1 play a key role in division by regulating Dnm1 self-assembly
Title: Mdv1 interacts with assembled dnm1 to promote mitochondrial division.

Preferred Names: Mdv1p

NP_012423.1

Peripheral protein of cytosolic face of mitochondrial outer membrane; required for mitochondrial fission; interacts with Fis1p and with the self-assembled oligomeric form of the dynamin-related GTPase Dnm1p; contains WD repeats; MDV1 has a paralog, CAF4, that arose from the whole genome duplication
