Fibronectin type II domain is a

cell differentiation and migration; maintenance of the cellular cytoskeleton; and tumour metastasis.[2] The major part of the sequence of fibronectin consists of the repetition of three types of domains, which are called type I, II, and III.[3]

Type II domain is approximately sixty amino acids long,

blood coagulation factor XII; bovine seminal plasma proteins PDC-109 (BSP-A1/A2) and BSP-A3;[5] cation-independent mannose-6-phosphate receptor;[6] mannose receptor of macrophages;[7] 180 Kd secretory phospholipase A2 receptor;[8] DEC-205 receptor;[9] 72 Kd and 92 Kd type IV collagenase (EC 3.4.24.24);[10] and hepatocyte growth factor activator.[11]

Fibronectin type II domain and Lipid bilayer interaction

Fibronectin type II domain is part of the extracellular portions of EphA2 receptor proteins. FN2 domain on EphA2 receptors bears positively-charged components, namely K441 and R443, which attract and almost exclusively bind to anionic lipids such as anionic membrane lipid phosphatidylglycerol.[12] K441 and R443 together make up a membrane-binding motif that allows EphA2 receptors to attach to the cell membrane.[12]
