COLQ Minigene Constructs for Spliceosomal Studies

Check if the same lab product or an alternative is used in the 5 most similar protocols
We constructed E15E16 (wt and p.E415G) minigenes spanning COLQ exon 15 to 16 and E16E17 (wt and p.E415G) minigenes spanning COLQ exon 16 to 17 in pcDNA3.1D/V5-His-TOPO vector (Invitrogen). Amplicons were generated by PCR using pCI-COLQ (wt or p.E415G), and cloned into pcDNA3.1D/V5-His-TOPO vector.
We introduced three copies MS2-coat protein binding hairpin sequences at the 3′ end of E16E17 (wt and E415G) constructs using the megaprimer method45 (link). At first, we PCR-amplified a fragment harboring three copies MS2-coat protein binding hairpin sequences from pSP64-MS2 vector35 (link) with the primers carrying complementary sequences to E16E17 minigene where the MS2-sequences is being inserted. The PCR amplicon was used as a megaprimer for the QuikChange site-directed mutagenesis system. These vectors were used as templates to generate MS2-attached RNA substrates of E16E17 (wt and p.E415G) for isolation of early spliceosomal complex. As control, we used MS2-attached human β-globin exon 1-intron 1-exon 2 construct (pSP64-HβΔ6-MS2) as previously described35 (link).

A human wild-type (WT) ACVR1 expression plasmid was generated by cloning the protein-coding sequence of human ACVR1 into pcDNA 3.1 D V5-His-TOPO vector (Invitrogen) and the ACVR1 R206H plasmid generated by site-directed mutagenesis of the WT ACVR1 [15 (link)]. This same approach was used with the indicated oligonucleotides (with mutant nucleotide underlined) for ACVR1 constitutively active (CA) (forward 5′: GTACAAAGAACAGTGGCTCGCGATATTACACTG-3′, reverse 5′: GCGAGCCACTGTTCTTTGTACCAGAAAAGGAAG-3′); ACVR1 G328E (forward 5′: GATATTTGGGACCCAAGAGAAACCAGCCATTGC-3′; reverse 5′: CTTGGGTCCCAAATATCTCTATGTGCAAATGTGC-3′); ACVR1 G328W (forward 5′: GATATTTGGGACCCAATGGAAACCAGCCATTGC-3′; reverse TTGGGTCCCAAATATCTCTATGTGCAAATGTGCT-3′); ACVR1 G356D (forward 5′: TTGCATAGCAGATTTGGACCTGGCAGTCATGC-3′; reverse 5′:CCAAATCTGCTATGCAACACTGTCCATTCTTCT-3′). The pSmad1/5/8-responsive BRE luciferase reporter (BRE-Luc; [17 (link)]) was used in the luciferase reporter gene assay with the pRL-TK renilla luciferase (Renilla-Luc) expression construct (Promega) as a control.
To generate ACVR1 ligand-binding domain deletion (ΔLBD) expression plasmids, amino acids 35–99, encoding the ligand-binding domain of the ACVR1 receptor, were deleted from full-length expression plasmids by site-directed mutagenesis PCR; an HA-tag was inserted at the N-terminal end of the protein [14 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
