3.A.2.2.4
The ubiquitous 14 subunit vacuolar H+-ATPase, V1/V0, has been implicated in various human diseases including osteopetrosis, renal tubule acidosis, and cancer (Hinton et al., 2009).  The transmembrane enzyme, Ribonuclease kappa, RNASEK (137 aas; 2 TMSs; UniProt acc# Q6P5S7), closely associates with the V-ATPase and is required for its function; its loss prevents the early events of endocytosis and the replication of multiple pathogenic viruses (Perreira et al. 2015).
