As a proof of principle for the functional relevance of genes directly or indirectly regulated by miR-137 in BPs, we focused on two genes, Cd63 (among the most induced genes in BPs; Figure S2A) and Myt1l (among the most repressed genes in BPs; Figure S2A), which encode an extracellular matrix receptor (Tschoepe et al., 1990) and a transcription factor critical for neuronal identity (Mall et al., 2017), respectively. Here, CD63 is linked to Bartsocas-Papas syndrome 1.
