Molecular cloning and characterization of three cDNAs encoding allatostatin-like neurosecretory peptides from Pandalopsis japonica

Involvement of a putative allatostatin in regulation of juvenile hormone titer and the larval development in Leptinotarsa decemlineata (Say)

“…In this study, we cloned LdAS-C and LdAS-B in L. decemlineata. Only a single copy of AS-B gene had been identified in each arthropod species except Pandalopsis japonica (Salma et al, 2012). In contrast, two genes encoding allatostatin C-like peptide (AS-C and AS-CC) were found in the tick Ixodes scapularis as well as dipteran, lepidopteran, coleopteran, hemipteran and phthirapteran insect species (Veenstra, 2009).…”

“…However, many of these peptides are multifunctional and act in a species-specific manner (Salma et al, 2012). In this study, we cloned LdAS-C and LdAS-B in L. decemlineata.…”

“…AS peptides have been classified into A, B and C types based on conserved structural characteristics (Stay and Tobe, 2007;Salma et al, 2012;Wang et al, 2012). Type A AS (FGLamides, AS-A) peptides have conserved pentapeptide sequence (Y/F)XFG(L/I)amide at the carboxy-terminus (Woodhead et al, 1989).…”
