ARMC8 Proteins and Enzymes

ARMC8 (armadillo-repeat-containing protein 8) is part of the conserved CTLH protein complex, where it is present as two alternatively spliced forms: ARMC8alpha and ARMC8beta. Studies have indicated that ARMC8alpha promotes protein degradation by both the proteasome-dependent and the vacuole/lysosome-dependent pathways, by interacting directly with the protein to be degraded or by associating with the monoubiquitin-binding protein HRS respectively. (The CTLH complex is also surmised to be involved in microtubule dynamics.)
