== Function ==
[https://www.uniprot.org/uniprot/NP_CIMLE NP_CIMLE] Heme-based protein that delivers nitric oxide gas (NO) to the victim while feeding, resulting in vasodilation (Probable). In place of heme, the heme-binding cysteine can also reversibly bind NO when it is present in high concentrations (PubMed:15637157).<ref>PMID:15637157</ref>
