UniprotKB/SwissProt ID: Q6PB97 (Q6PB97)
Gene Name:
Fbxl19
Organism: Mus musculus (Mouse)
Function: Substrate-recognition component of the SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin ligase complex that plays a role in different processes including cell migration, cell proliferation or cytoskeletal reorganization (PubMed:28453857, PubMed:29809150). Mediates RHOA ubiquitination and degradation in a ERK2-dependent manner. Induces RAC1 and RAC3 degradation by the proteasome system and thereby regulates TGFB1-induced E-cadherin down-regulation and cell migration. Also mediates ubiquitination and degradation of IL-33-induced receptor IL1RL1 and subsequently blocks IL-33-mediated apoptosis (PubMed:22660580). Within the nucleus, binds to DNA containing unmethylated cytidine-phosphate-guanosine (CpG) dinucleotides (PubMed:28453857, PubMed:29809150). Recruits CDK-mediator to chromatin and targets CDK8 to promoters of silent developmental genes leading to induction of these genes during cell differentiation (PubMed:29809150). In addition, plays a critical role in the recruitment of RNF20 to histone H2B leading to H2B mono-ubiquitination (PubMed:28453857)
