Long NPF has been cloned in Rhodnius (RhoprNPF) and is conserved across arthropods.
RhoprNPF is predominantly expressed in the CNS and gut of instars and adults.
12 paired cells express RhoprNPF transcript in the brain of instars and adults.
Adult female lateral oviducts contain cells that express RhoprNPF.
RhoprNPF and FM/IRFamides increase egg production whereas MS and AST inhibit.
