Figure Legend Snippet: a) WebLogo ( http://weblogo.berkeley.edu/ ) representation of the 10bp motif discovered by the PRIORITY motif finder in the ChIP peak sequences. The height of each letter represents the enrichment of that base at each position. If all four bases are equally represented, no base is shown at that position. b) Competition EMSA analysis of CaRF binding to the consensus chCaRE motif in the ChIP peak of the Camk2n1 gene (camCaRE). Arrow indicates the CaRF-camCaRE complex, and the right triangles indicate increasing concentrations (50 or 100 fold molar excess) of the unlabeled competitor probes. c) Competition EMSA analysis to examine the relative importance of each base across the 10bp chCaRE motif. Recombinant CaRF was incubated with radiolabeled camCaRE in the absence (-) or presence of a 50 or 100-fold molar excess of unlabeled competitor probes. The right triangle indicates increasing competitor concentrations. Competitor probes were based on the camCaRE sequence ( AAAGCGAGGC ) with the indicated changes at each position (e.g. 1G has a G rather than an A at position 1 of the motif while the rest of the motif is unchanged). Degenerate code: Y = C/T, N = A,C,G, or T, B = C,G, or T, R = A/G, H = A, C, or T, D = A, G, or T. d) Alignment of the cCaRE, mCaRE, chCaRE, and camCaRE sequences. The mCaRE, which fails to bind CaRF, differs from the CaRF binding sequences at 5 positions, which are shown in gray. Degenerate bases are as described above along with S = C/G.
Techniques Used: Binding Assay, Recombinant, Incubation, Sequencing
Figure Legend Snippet: a) Primary data from the UCSC genome browser ( http://genome.ucsc.edu ) showing the CaRF ChIP peak overlapping exon 1 of the Carf gene. b) Position of CaRF-binding motifs in the CaRF ChIP peak from the Carf gene. Capital letters denote exon 1. The underlined sequences show the two potential CaRF-binding motifs. The more 3′ motif in intron 1 was identified by the PRIORITY motif finder. c) Competition EMSA analysis demonstrates that CaRF can bind both motifs in the Carf ChIP peak. Recombinant CaRF was bound to a radiolabeled cCaRE probe in the absence (-) or presence of a 100-fold molar excess of competitor probes. Arrow indicates the CaRF-cCaRE complex. Unlabeled probes used as competitors are listed across the top. d) Expression of Carf mRNA in a Carf exon 8 KO mouse. Cortical neurons from individual P0 WT or CaRF exon 8 deleted (KO) mice were cultured for 5 days, treated with 1µM TTX overnight, then RNA was harvested for cDNA synthesis and quantitative PCR. Carf mRNA was detected with primers against exons 11–12 distal to the deleted region in Carf . Carf mRNA expression was normalized for expression of Gapdh in the same sample to control for sample handling. e) Chromatin immunoprecipitation for RNA polymerase II on the Carf promoter. Carf promoter DNA co-precipitated with an anti-RNA polymerase II antibody or control IgG was quantitated by Q-PCR, and normalized as a percent of signal in the input DNA. Bars show the mean and error bars show SEM. * p <0.05.
