The function of GNL2 (G protein nucleolar 2, ENSG00000134697) is as follows. GTPase that associates with pre-60S ribosomal subunits in the nucleolus and is required for their nuclear export and maturation (PubMed:32669547). May promote cell proliferation possibly by increasing p53/TP53 protein levels, and consequently those of its downstream product CDKN1A/p21, and decreasing RPL23A protein levels (PubMed:26203195). {ECO:0000269|PubMed:26203195, ECO:0000269|PubMed:32669547}.
