Functioni

Scaffolding protein that enhances integrin activation mediated by TLN1 and/or TLN2, but activates integrins only weakly by itself. Binds to membranes enriched in phosphoinositides. Enhances integrin-mediated cell adhesion onto the extracellular matrix and cell spreading; this requires both its ability to interact with integrins and with phospholipid membranes. Required for the assembly of focal adhesions. Participates in the connection between extracellular matrix adhesion sites and the actin cytoskeleton and also in the orchestration of actin assembly and cell shape modulation. Recruits FBLIM1 to focal adhesions. Plays a role in the TGFB1 and integrin signaling pathways. Stabilizes active CTNNB1 and plays a role in the regulation of transcription mediated by CTNNB1 and TCF7L2/TCF4 and in Wnt signaling.3 Publications

Disruption phenotypei

Complete embryonic lethality at peri-implantation stage, due to severe detachment of the endoderm and epiblast from the basement membrane. Heterozygous mice lacking one copy of Fermt2 show no visible phenotype, but show decreased tumor angiogenesis upon transplantation of tumor cells, and their blood vessels are abnormally leaky.3 Publications

Domaini

The FERM domain is not correctly detected by PROSITE or Pfam techniques because it contains the insertion of a PH domain.
The PH domain binds phospholipids. Binds preferentially phosphatidylinositol-3,4,5-trisphosphate, and has lower affinity for phosphatidylinositol-4,5-bisphosphate (By similarity).By similarity
The N-terminal region displays a ubiquitin-type fold and mediates interaction with membranes containing negatively charged phosphatidylinositol phosphate via a surface enriched in positively charged residues.By similarity
