Transgene overexpression of fem-3 leads to extensive masculinization of XX soma. [Hodgkin 1986; Ahringer et al. 1992; CB; JK; AS]
Enables protein phosphatase binding activity. Involved in several processes, including protein localization to chromatin; regulation of reproductive process; and sex determination. Located in cytoplasm and protein-containing complex. Expressed in germ line; spermatid; and in male.
