FIG. 5.

Physiological activities of wild-type per and perΔ are very similar in flies with accelerated nuclear translocation of PER. Representation of grouped locomotor activity in constant darkness of pdf-GAL4-UAS-sgg [from EP (X) 1576], exhibiting shortening of the period (a); pdf-GAL4-UAS-sgg-UAS-per24, exhibiting normal period (b); and pdf-GAL4-UAS-sgg-UAS-perΔ, having normal period (c). Three independent lines of UAS-perΔ are shown here. A complete summary of UAS-perΔ lines tested is in Table 3.
