Summary: Bombolitin family
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
Bombolitin family Provide feedback
This family consists of the bombolitin peptides that are found in the venom of the bumblebee Megabombus pennsylvanicus. Bombolitins are structurally and functionally very similar. They lyse erythrocytes and liposomes, release histamine from rat peritoneal mast cells, and stimulate phospholipase A2 from different sources .

This family consists of the bombolitin peptides that are found in the venom of the bumblebee Megabombus pennsylvanicus (American common bumblebee). Bombolitins are structurally and functionally very similar. They lyse erythrocytes and liposomes, release histamine from rat peritoneal mast cells, and stimulate phospholipase A2 from different sources [PUBMED:2578459].

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
