Predicted to enable several functions, including RNA binding activity; mRNA cap binding complex binding activity; and polysome binding activity. Predicted to be involved in negative regulation of transposition; piRNA metabolic process; and spermatogenesis, exchange of chromosomal proteins. Predicted to act upstream of or within spermatogenesis. Predicted to be located in chromatoid body; dense body; and nucleus. Orthologous to human PIWIL1 (piwi like RNA-mediated gene silencing 1).
