The function of FBXO24 (F-box protein 24, ENSG00000106336) is as follows. Substrate recognition component of an SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex that mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Specifically recognizes the deacetylated form of nucleoside diphosphate kinase A/NME1 and targets it for ubiquitin-mediated degradation (PubMed:25582197). Functions as a key regulator of cell proliferation by targeting PRMT6 for ubiquitination and proteasomal degradation, leading to cell cycle inhibition (PubMed:32828318). Also mediates 'Lys-6'-linked polyubiquitination of the mitochondrial S- adenosylmethionine transporter SLC25A26, targeting it for degradation and thereby maintaining mitochondrial function during spermiogenesis (By similarity). Promotes ubiquitination and degradation of mitochondrial aspartyl-tRNA synthetase DARS2, contributing to immunosuppressive activity (PubMed:39039092). In the nucleus, targets FOXK2 for ubiquitin-mediated degradation, a process that critically modulates mitochondrial respiration and cellular bioenergetics in lung epithelial cells (PubMed:38735474). {ECO:0000250|UniProtKB:Q9D417, ECO:0000269|PubMed:25582197, ECO:0000269|PubMed:32828318, ECO:0000269|PubMed:38735474, ECO:0000269|PubMed:39039092}.
