General annotation (Comments)
| Function | Transcriptional repressor which preferentially binds to the GC-rich consensus sequence (5'-AGCCCCCGGCG-3') and may regulate expression of TNF, EGFR and PDGFA. May control smooth muscle cells proliferation following artery injury through PDGFA repression. May also bind double-stranded RNA. Positively regulates Toll-like receptor (TLR) signaling in response to agonist probably by competing with the negative FLII regulator for MYD88-binding. Ref.1 Ref.5 Ref.6 Ref.7 Ref.11 |
| Subunit structure | Interacts with FLII. Interacts with MYD88. Competes with FLII for MyD88-binding, even in the absence of LPS. Ref.2 Ref.11 |
| Subcellular location | |
| Tissue specificity | |
| Developmental stage | Widely expressed in fetal tissues. Ref.2 |
| Sequence similarities | Belongs to the LRRFIP family. |
| Sequence caution | The sequence AAH01385.1 differs from that shown. Reason: Contaminating sequence. Potential poly-A sequence. The sequence AAY14672.1 differs from that shown. Reason: Erroneous gene model prediction. |
