During sexual reproduction in most animals, oocytes arrest in
meiotic prophase and resume meiosis (meiotic maturation) inresponse to
sperm or somatic cell signals. Despite progress indelineating
mitogen-activated protein kinase (MAPK) and CDK/cyclinactivation
pathways involved in meiotic maturation, it is lessclear how these
pathways are regulated at the cell surface. TheCaenorhabditis
elegans major sperm protein (MSP) signals oocytes,which are
arrested in meiotic prophase, to resume meiosis andovulate. We used
DNA microarray data and an in situ binding assayto identify the VAB-1
Eph receptor protein-tyrosine kinase asan MSP receptor. We show that
VAB-1 and a somatic gonadal sheathcell-dependent pathway, defined by
the CEH-18 POU-class homeoprotein,negatively regulate meiotic
maturation and MAPK activation. MSPantagonizes these inhibitory
signaling circuits, in part by bindingVAB-1 on oocytes and sheath
cells. Our results define a sperm-sensingcontrol mechanism that
inhibits oocyte maturation, MAPK activation,and ovulation when sperm
are unavailable for fertilization. MSP-domainproteins are found in
diverse animal taxa, where they may regulatecontact-dependent Eph
receptor signaling pathways.
