Prominin Provide feedback
The prominins are an emerging family of proteins that among the multispan membrane proteins display a novel topology. Mouse prominin and human prominin (mouse)-like 1 (PROML1) are predicted to contain five membrane spanning domains, with an N-terminal domain exposed to the extracellular space followed by four, alternating small cytoplasmic and large extracellular, loops and a cytoplasmic C-terminal domain . The exact function of prominin is unknown although in humans defects in PROM1, the gene coding for prominin, cause retinal degeneration .

InterPro entry IPR008795The prominins are an emerging family of proteins that, among the multispan membrane proteins, display a novel topology. Mouse and Homo sapiens prominin and (Mus musculus) prominin-like 1 (PROML1) are predicted to contain five membrane spanning domains, with an N-terminal domain exposed to the extracellular space followed by four, alternating small cytoplasmic and large extracellular, loops and a cytoplasmic C-terminal domain [PUBMED:11467842]. The exact function of prominin is unknown although in humans defects in PROM1, the gene coding for prominin, cause retinal degeneration [PUBMED:10587575].

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
