Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables several functions, including RNA binding activity; mRNA cap binding complex binding activity; and protein kinase binding activity. Involved in piRNA-mediated retrotransposon silencing by heterochromatin formation; primary piRNA processing; and sperm DNA condensation. Located in chromatoid body; dense body; and nucleus. Is expressed in several structures, including central nervous system; genitourinary system; hemolymphoid system gland; and lung. Orthologous to human PIWIL1 (piwi like RNA-mediated gene silencing 1).
