FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes an RNA-binding phosphoprotein that is part of the MEX3 (muscle excess 3) family of translational regulators. The encoded protein contains N-terminal nuclear export and nuclear localization signals and is exported from the cytoplasm to the nucleus. The protein binds to RNA via two KH domains and also colocalizes with MEX3A, Dcp1A decapping factor and Argonaute proteins within P (processing) bodies. [provided by RefSeq, Oct 2012]
PHENOTYPE: Homozygous inactivation of this gene leads to partial neonatal lethality, decreased body weight and subfertility. Males show seminiferous tubule obstruction, oligozoospermia, abnormalities in Sertoli cell barrier morphology and function, and impaired Sertoli cell and macrophage phagocytosis.
