Functional selectivity of glial protrusion-localized transcripts. (A) Comparison of glial protrusion-localized transcripts (1,740 genes) with the mouse Perisynaptic Schwann Cell (PSC) transcriptome (Castro et al., 2020). For PSC RNA-seq data, TPM >10 cutoff was used for RNA expression and the recovered genes were converted to fly genes with DIOPT score ≥8 cutoff. (B) Under-representation of housekeeping genes in the glial protrusion-localized transcripts. Housekeeping Gene Ontology (GO) terms were selected from (Joshi et al., 2022), and the enrichment or under-representation of each term was assessed using a hypergeometric test.
