Fermitin-2 (FERMT2 / Kindlin-2)

🔬 Protein Info
Gene SymbolFERMITIN2
AliasesFERMITIN2PROTEIN
Subcellular Localizationto the plasma membrane through phosphatidylinositol (PIP2) binding
GeneCardsFERMITIN2
Human Protein AtlasFERMITIN2
Kindlin-1 (FERMT1)Epithelial expression — mutations cause Kindler syndrome
Kindlin-3 (FERMT3)Hematopoietic expression — essential for platelet and immune cell integrin activation
Inside-out signalingIn response to cellular cues, fermitin-2 is recruited to integrin cytoplasmic tails via its FERM domain
Integrin primingBinding to the β cytoplasmic tail relieves the autoinhibited state of the integrin heterodimer
Talin cooperationThe talin-fermitin-2 partnership is the validated mechanism for converting inactive into active integrins
Ligand bindingActivated integrins bind to ECM proteins (fibronectin, collagen, laminin) with high affinity
Adhesome recruitmentFermitin-2 recruits paxillin, vinculin, and other adhesion proteins to nascent focal adhesions
Actin linkageVia its C-terminal region, fermitin-2 links activated integrins to the actin cytoskeleton
Focal adhesion maturationPromotes growth and stabilization of focal adhesions through mechanosensing
Turnover regulationControls focal adhesion disassembly during cell migration
