RFFL

RFFL (Ring Finger And FYVE Like Domain Containing E3 Ubiquitin Protein Ligase) is a Protein Coding gene. Among its related pathways are Gene Expression and Regulation of TP53 Activity. Gene Ontology (GO) annotations related to this gene include protein kinase binding and ubiquitin protein ligase binding. An important paralog of this gene is RNF34.

ring finger and FYVE-like domain containing 1

E3 ubiquitin-protein ligase that regulates several biological processes through the ubiquitin-mediated proteasomal degradation of various target proteins. Mediates 'Lys-48'-linked polyubiquitination of PRR5L and its subsequent proteasomal degradation thereby indirectly regulating cell migration through the mTORC2 complex. Ubiquitinates the caspases CASP8 and CASP10, promoting their proteasomal degradation, to negatively regulate cell death downstream of death domain receptors in the extrinsic pathway of apoptosis. Negatively regulates the tumor necrosis factor-mediated signaling pathway through targeting of RIPK1 to ubiquitin-mediated proteasomal degradation. Negatively regulates p53/TP53 through its direct ubiquitination and targeting to proteasomal degradation. Indirectly, may also negatively regulate p53/TP53 through ubiquitination and degradation of SFN. May also play a role in endocytic recycling.

The FYVE-type zinc finger may mediate phosphatidylinositol phosphate-binding and control subcellular localization.

Autoubiquitinated.
Palmitoylated.
Undergoes caspase-mediated cleavage upon death-receptor activation, by TNFSF10 for instance. May be mediated by the caspases CASP8 and CASP10 in a negative feedback loop.
