Where clause in generic method

I have a generic method that takes 2 generics parameters: BType and IType. Is there a way to define in the method signature that BType has to be a implementation of IType?!?

Edit1: here the method signature:

public static Expression<Func<BType, bool>> CastFunc<BType,IType>(Expression<Func<IType, bool>> customWhereClause)

public static Expression<Func<BType, bool>> CastFunc<BType,IType>(Expression<Func<IType, bool>> customWhereClause) where BType : IType
