Absence of the I-10 protein segment mediates restricted dimerization of the cartilage-specific fibronectin isoform.

Abstract excerpt

The cartilage-specific (V + C)(-) fibronectin isoform does not efficiently heterodimerize with other V-region splice variants of fibronectin. To understand better the structural elements that determine this restricted dimerization profile, a series of truncated fibronectin expression constructs with various internal deletions in the V, III-15, or I-10 segments were constructed and co-transfected into COS-7 cells...
