Research Backgrounds

Function:

Plays a role in mitochondrial and peroxisomal fission. Promotes the recruitment and association of the fission mediator dynamin-related protein 1 (DNM1L) to the mitochondrial surface. May be involved in regulation of synaptic vesicle membrane dynamics by recruitment of DNM1L to clathrin-containing vesicles.

Subcellular Location:

Mitochondrion outer membrane>Single-pass type IV membrane protein. Peroxisome. Cytoplasmic vesicle>Secretory vesicle>Synaptic vesicle.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Tissue Specificity:

Highly expressed in heart, kidney, liver, brain, muscle, and stomach.

Subunit Structure:

Homodimer. Interacts with DNM1L (By similarity).

Family&Domains:

Belongs to the Tango11 family.
