WormMine: ExpressionPattern Expr1892

• Pattern: FBF-1 is present uniformly in germline cytoplasm during early larval stages, and becomes enriched in the mitotic region of L4 larval and adult germ lines. There is no detectable staining in an fbf-1 single mutant. Within the mitotic region of wild-type germ lines, the distalmost germ cells possess faint but easily detectable FBF-1 staining, which becomes intense in more proximal mitotic cells. As germ cells leave the mitotic region and enter early meiotic prophase, FBF-1 is reduced to a low level. This pattern is similar in males.
