Biochem/physiol Actions

Fibronectin Type III Connecting Segment (IIICS) is responsible for melanoma cell adhesion. It is the predominant binding site of integrin α4β1, which is mediated through the aspartic acid residue present at position 21. Studies in chicken show that alternative splicing in this region during development of the peripheral nervous system, is essential for the control cell-cell adhesion.

General description

Fibronectin is composed of two cell adhesion domains namely, the central domain for cell-binding made of adhesion-recognizing tetrapeptide, and the alternatively spliced type III connecting segment (IIICS). It contains a tetrapeptide region, from amino acid 90-109, called CS5, which is essential for adhesion mediated by IIICS. Both CS5 and CS1 mediate melanoma cell spreading, when stimulated by immunoglobulin (Ig)G, with CS1 exhibiting higher activity.

A 29-kDa monomeric dispase-digestive fragment of human plasma fibronectin has been purified by heparin affinity chromatography. The NH2-terminal sequence was determined as Ala1687-Val-Thr-Thr-Ile-Pro-Ala-Pro. By mass spectrometry the molecular weight was determined to be 30,241.9 with standard deviation of 3.9 amu.

Here we show striking differences in conformational regulation among beta1 integrins. Upon manganese stimulation, a beta1 epitope defined by monoclonal antibody (mAb) 9EG7 was induced strongly (on alpha4beta1), moderately (on alpha5beta1), weakly (on alpha2beta1), or was scarcely detectable (on alpha6beta1

Fibronectin contains at least two domains that support cell adhesion. One is the central cell-binding domain that is recognized by a variety of cell types, including fibroblasts. The second, originally identified by its ability to support melanoma cell adhesion, is
