Hybridization of S6k cDNA sequences to Drosophila genomic DNAs. DNA samples derived from fly strains y w^67c23; H{Lw2}55A (blot A only), y w^67c23; H{Lw2}D85.6b, y w^67c23; H{Lw2}J9.102 and y w^67c23; Gla/SM6a(20) were digested with the restriction enzymes indicated above the lanes and probed with the following sequences. (A) N-terminal S6k cDNA (spanning subdomain II) and 5′-UTR sequences (common to class 1 and 2 S6k cDNAs). (B) Catalytic domain sequences. (C) C-terminal (from subdomain XI) and 3′-UTR sequences. B, BamHI; X, XhoI; N, NsiI; H, HindIII; Nd, NdeI.
