Column 1 represents gene name, column 2 – known function of the gene, column 3 – GCL enrichment at P3, column 4 – consistent GCL enrichment (at least at 4 out of 5 ages) from P0-P22. Fifth column shows whether the gene is regulated by Brn3a at P3, 6th – regulated by Brn3a at any of 5 studied ages. Columns 7, 8 and 9 represent the onset, the peak and the offset respectively of postnatal gene expression in the GCL. Column 10 shows whether the gene is highly and sparsely expressed in the GCL at any of studied ages. Columns 11 and 12 identify the genes that had unregulated transcripts or exhibited gene level regulation by RNASeq
