Component of the large ribosomal subunit (PubMed:12962325, PubMed:23636399, PubMed:25901680, PubMed:25957688, PubMed:32669547). The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell (PubMed:12962325, PubMed:23636399, PubMed:25901680, PubMed:25957688, PubMed:32669547). {ECO:0000269|PubMed:23636399, ECO:0000269|PubMed:25901680, ECO:0000269|PubMed:25957688, ECO:0000269|PubMed:32669547, ECO:0000305|PubMed:12962325}. Inhibits C2CD2L/TMEM24-dependent transport of phosphatidylinositol, the precursor of phosphatidylinositol 4,5- bisphosphate (PI(4,5)P2), from its site of synthesis in the endoplasmic reticulum to the cell membrane (PubMed:33479206). This leads to down- regulation of the PI3K-AKT-mTOR signaling pathway (PubMed:33479206). . This is the function of Ensembl gene identifier ENSG00000130255 (RPL36, ribosomal protein L36).
