Summary

FBXL14 (F-box and leucine rich repeat protein 14, HGNC:28624) is a protein-coding gene on chromosome 12p13.33, encoding F-box/LRR-repeat protein 14 (Q8N1E6). Substrate-recognition component of some SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin-protein ligase complexes.

Members of the F-box protein family, such as FBXL14, are characterized by an approximately 40-amino acid F-box motif. SCF complexes, formed by SKP1 (MIM 601434), cullin (see CUL1; MIM 603134), and F-box proteins, act as protein-ubiquitin ligases. F-box proteins interact with SKP1 through the F box, and they interact with ubiquitination targets through other protein interaction domains (Jin et al., 2004 [PubMed 15520277]).

  • Data show that Twist1 small interfering RNA prevents hypoxia-induced Fbxl14 down-regulation and SNAIL1 stabilization. (PMID:19955572)
  • USP13 and FBXL14 play opposing roles in the regulation of glioma stem cells (GSCs) through reversible ubiquitination of c-Myc. (PMID:27923907)
  • induced FBXL13 expression downregulates centrosomal gamma-tubulin and disrupts centrosomal microtubule arrays. In addition, depletion of FBXL13 induces high levels of CEP192 and gamma-tubulin at the centrosomes with the consequence of defects in cell motility. (PMID:29348145)
  • FBXL14 acts as an novel interaction partner of CDCP1, and facilitates its ubiquitination and proteasomal degradation with an enhanced capacity to suppress CDCP1 protein stability that eventually prevents CDCP1 target genes involved in breast cancer metastasis. (PMID:29973690)
  • Loss of FBXL14 promotes mesenchymal shift and radioresistance of non-small cell lung cancer by TWIST1 stabilization. (PMID:34285182)

UniProt curated annotations — full annotation on UniProt →

Function. Substrate-recognition component of some SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin-protein ligase complexes. The SCF(FBXL14) complex acts by mediating ubiquitination and subsequent degradation of SNAI1.

Subunit / interactions. Part of a SCF (SKP1-cullin-F-box) ubiquitin-protein ligase complex. Interacts with SKP1 and CUL1. Interacts with SNAI1; the interaction requires the phosphorylation of the two serine residues in the substrate destruction motif D-S-G-X(2,3,4)-S.

Subcellular location. Cytoplasm.

Induction. Down-regulated by hypoxia.
