The protein encoded by this gene is a member of the
immunoglobulin superfamily. The protein contains six immunoglobulin-like domains and thirteen
fibronectin type III domains. Fibronectin type III domains are present in both
extracellular and intracellular proteins and tandem repeats are known to contain binding sites for
DNA,
heparin and the cell surface. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2016]. == References ==
