VPS11

Vesicle mediated protein sorting plays an important role in segregation of intracellular molecules into distinct organelles. Genetic studies in yeast have identified more than 40 vacuolar protein sorting (VPS) genes involved in vesicle transport to vacuoles. This gene encodes the human homolog of yeast class C Vps11 protein. The mammalian class C Vps proteins are predominantly associated with late endosomes/lysosomes, and like their yeast counterparts, may mediate vesicle trafficking steps in the endosome/lysosome pathway.

vacuolar protein sorting 11 homolog (S. cerevisiae)

Plays a role in vesicle-mediated protein trafficking to lysosomal compartments including the endocytic membrane transport and autophagic pathways. Believed to act as a core component of the putative HOPS and CORVET endosomal tethering complexes which are proposed to be involved in the Rab5-to-Rab7 endosome conversion probably implicating MON1A/B, and via binding SNAREs and SNARE complexes to mediate tethering and docking events during SNARE-mediated membrane fusion. The HOPS complex is proposed to be recruited to Rab7 on the late endosomal membrane and to regulate late endocytic, phagocytic and autophagic traffic towards lysosomes. The CORVET complex is proposed to function as a Rab5 effector to mediate early endosome fusion probably in specific endosome subpopulations (PubMed:11382755, PubMed:23351085, PubMed:24554770, PubMed:25266290, PubMed:25783203).
Required for fusion of endosomes and autophagosomes with lysosomes (PubMed:25783203).
Involved in cargo transport from early to late endosomes and required for the transition from early to late endosomes (PubMed:21148287).
Involved in the retrograde Shiga toxin transport (PubMed:23593995).

Leukodystrophy, hypomyelinating, 12 (HLD12):
An autosomal recessive neurologic disorder characterized by developmental delay, spasticity, truncal hypotonia, acquired microcephaly, intellectual disability with variable seizure disorder, accompanied by thin corpus callosum, paucity of white matter and delayed myelination.
Dystonia 32 (DYT32):
A form of dystonia, a disorder defined by the presence of sustained involuntary muscle contraction, often leading to abnormal postures. DYT32 is an autosomal recessive, slowly progressive form with onset in adulthood and generalized involvement of the limbs, trunk, neck, and larynx, resulting in dysarthria and dysphagia. Brain imaging may show abnormalities in the basal ganglia.
