Clustered mitochondria Provide feedback
The CLU domain (CLUstered mitochondria) is a eukaryotic domain found in proteins from fungi, protozoa, plants to humans. It is required for correct functioning of the mitochondria and mitochondrial transport [1,2] although the exact function of the domain is unknown . In Dictyostelium the full-length protein is required for a very late step in fission of the outer mitochondrial membrane  suggesting that mitochondria are transported along microtubules, as in mammalian cells, rather than along actin filaments, as in budding yeast . Disruption of the protein-impaired cytokinesis and caused mitochondria to cluster at the cell centre . It is likely that CLU functions in a novel pathway that positions mitochondria within the cell based on their physiological state. Disruption of the CLU pathway may enhance oxidative damage, alter gene expression, cause mitochondria to cluster at microtubule plus ends, and lead eventually to mitochondrial failure .

The CLU domain (CLUstered mitochondria) is a eukaryotic domain found in highly conserved eukaryotic proteins required for correct mitochondrial dispersal [PUBMED:9207087, PUBMED:12952081]. The exact function of the domain is unknown [PUBMED:20457612].

We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request
