Copies of the domain are also found in some baculoviruses. Relevant references that describe proteins with this domain include [1-3]. It is an extracellular domain that contains six conserved cysteines that probably form three disulphide bridges. Chitin binding has been demonstrated for a protein containing only two of these domains [1].
