Identification of Crustacean Female Sex Hormone Receptor Involved in Sexual Differentiation of a Hermaphroditic Shrimp.

ABSTRACT: The neurohormone crustacean female sex hormone (CFSH) contains a highly conserved interleukin-17 (IL-17) domain in the mature peptide. Although CFSH has been demonstrated to stimulate female sexual differentiation in crustaceans, its receptors (CFSHR) have been poorly reported. The present study identified an IL-17 receptor (named Lvit-IL-17R), a candidate of CFSHR, from the protandric simultaneous hermaphroditic (PSH) shrimp Lysmata vittata through GST pulldown assays and RNAi experiments. Lvit-IL-17R is a transmembrane protein with an SEFIR (similar expression as the fibroblast growth factor and IL-17R) domain, as determined through sequence analysis. A GST pulldown experiment confirmed the interactions between the type I CFSHs (CFSH1a and CFSH1b) and Lvit-IL-
