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

Nucleus. Cytoplasm Ref.2 Ref.6.

Tissue specificity

Ubiquitously expressed. Ref.1 Ref.2

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.
