PolyA-sequencing in Jurkat cells upon CDK12 depletion.

Project description:We analyzed the 3' end of polyadenylated transcripts in Jurkat cells treated with either THZ531 (vs. DMSO) or the CDK12 degrader BSJ-4-116 (vs. BSJ-4-116NC).

Heterochromatin remodeling by CDK12 contributes to learning in Drosophila

Project description:We describe the epigenetic profiling of the H3K9me2 and HP1a in Drosophila third instar larvae before and after CDK12 depletion by RNA interference (RNAi). Here we show that CDK12 regulates heterochromatin dynamics in Drosophila chromosomes. Depletion of CDK12 induces the increased HP1a and H3K9me2 binding profile on the coding region of euchromatic genes, with the X chromosome being the most affected. These results are consistent with the polytene chromosome immunostaining pattern of HP1a and H3K9me2 after CDK12 knockdown in our initial cytological observations, which show that CDK12 depletion induce heterochromatin spreading on euchromatic arms, especially on the X chromosome. This study describes a novel role of the CDK12 complex in controlling the epigenetic transition between euchromatin and heterochromatin. Examination of the genome-wide H3K9me2 and HP1a binding profile in wildtype larvae (WT) and CDK12-depleted larvae (CDK12-KD). Examination of the genome-wide CDK12 binding profile in wildtype larvae (WT). Twelve independent immunoprecipitations were conducted for each antibody. Two biological replicates were performed.

RNA-Seq of Drosophila melanogaster Cdk12-null mutants versus control

Project description:In a forward genetic screen, we have previously identified a null mutant of Cdk12 that results in alterations in actin dynamics, the axon initial segment and electrophysiology in Drosophila melanogaster. To decipher how Cdk12 may be having these effects, we extracted RNA from pooled Drosophila heads and compared Cdk12-null mutants to controls at the transcriptome level.
