total RNA |
| Extraction protocol |
Five replicates of RBP4-TRAP and VGAT-TRAP were harvested by rapid forebrain dissection at 21 days post birth as described (Ouwenga et al. 2017; Westmark et al. 2011). Each replicate contained a pool of two to three forebrains of both sexes as available. Four samples were collected from each replicate in parallel: whole cell homogenate (WCH) was RNA isolated from an aliquot of the initial homogenization of the tissue, TRAP was the capture of GFP-tagged ribosomes from an aliquot of WCH. RNA isolated from a fraction of the WCH subjected to synaptoneurosomal fractionation (SNF), and SynapTRAP (ST) is TRAP performed on the SNF, as described (Ouwenga et al. 2017). RNA concentration for all was measured using a Nanodrop and diluted to <5ng/µL before being assessed for quality and concentration using an Agilent TapeStation 4200
Library preparation was performed with 30ng of total RNA from each sample. ds-cDNA was prepared using the SMARTer Ultra Low RNA kit for Illumina Sequencing (Clontech #634936) per manufacturer’s protocol. cDNA was fragmented using a Covaris E220 sonicator using peak incident power 18, duty factor 20%, cycles/burst 50, time 120 seconds at 18 degrees. cDNA was blunt ended, had an A base added to the 3’ends, and then had Illumina sequencing adapters ligated to the ends. Ligated fragments were then amplified for 13 cycles using primers incorporating unique index tags.

| Data processing |
RNA-seq reads were aligned to the Ensembl top-level assembly with STAR version 2.0.4b (Dobin et al. 2013) (RRID:SCR_015899).
Gene counts were derived from the number of uniquely aligned unambiguous reads by Subread:featureCount version 1.4.5. Sequencing performance was assessed with RSeQC version 2.3 (L. Wang, Wang, and Li 2012) (RRID:SCR_005275) for total number of aligned reads, total number of uniquely aligned reads, genes and transcripts detected, ribosomal fraction, known junction saturation, and read distribution over known gene models.
