Summaries for FBXL2 Gene

Entrez Gene Summary for FBXL2 Gene

  • This gene encodes a member of the F-box protein family which is characterized by an approximately 40 amino acid motif, the F-box. The F-box proteins constitute one of the four subunits of ubiquitin protein ligase complex called SCFs (SKP1-cullin-F-box), which function in phosphorylation-dependent ubiquitination. The F-box proteins are divided into 3 classes: Fbws containing WD-40 domains, Fbls containing leucine-rich repeats, and Fbxs containing either different protein-protein interaction modules or no recognizable motifs. The protein encoded by this gene belongs to the Fbls class and, in addition to an F-box, contains 12 tandem leucine-rich repeats. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2010]

GeneCards Summary for FBXL2 Gene

FBXL2 (F-Box And Leucine Rich Repeat Protein 2) is a Protein Coding gene. Diseases associated with FBXL2 include Hepatitis C Virus. GO annotations related to this gene include ubiquitin-protein transferase activity and protein phosphatase binding. An important paralog of this gene is FBXL20.

UniProtKB/Swiss-Prot for FBXL2 Gene

  • Calcium-activated substrate recognition component of the SCF (SKP1-cullin-F-box protein) E3 ubiquitin-protein ligase complex, SCF(FBXL2), which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Unlike many F-box proteins, FBXL2 does not seem to target phosphodegron within its substrates but rather calmodulin-binding motifs and is thereby antagonized by calmodulin. This is the case for the cyclins CCND2 and CCND3 which polyubiquitination and subsequent degradation are inhibited by calmodulin. Through CCND2 and CCND3 degradation induces cell-cycle arrest in G(0) (PubMed:22020328, PubMed:22323446). SCF(FBXL2) also mediates PIK3R2 ubiquitination and proteasomal degradation thereby regulating phosphatidylinositol 3-kinase signaling and autophagy (PubMed:23604317). PCYT1A monoubiquitination by SCF(FBXL2) and subsequent degradation regulates synthesis of phosphatidylcholine, which is utilized for formation of membranes and of pulmonary surfactant (By similarity).

    Protein attributes for FBXL2 Gene

    Size:
    423 amino acids
    Molecular mass:
    47062 Da
    Quaternary structure:
    • Part of the SCF (SKP1-CUL1-F-box) E3 ubiquitin-protein ligase complex SCF(FBXL2) composed of CUL1, SKP1, RBX1 and FBXL2 (PubMed:10531037). Interacts with PCYT1A. Interacts with calmodulin; may antagonize substrate ubiquitination by SCF(FBXL2) (By similarity). Interacts with CCND2 and CCND3 (PubMed:22323446, PubMed:22020328). Interacts with PIK3R2; PIK3R2 is a substrate ubiquitinated by the SCF(FBXL2) complex (PubMed:23604317). May interact with PIK3R1 (PubMed:23604317). Interacts with PTPN13. Interacts with hepatitis C virus non-structural protein 5A (NS5A) and less efficiently, with hepatitis C virus non-structural protein 5B (NS5B); a reaction crucial for hepatitis C virus RNA replication (PubMed:15893726).
    Miscellaneous:
    • Deletion of the F-box domain creates a dominant-negative protein that inhibits replication of hepatitis C virus RNA when overexpressed in a hepatoma cell line; this inhibition could be overcome by NS5A coexpression.
