We are having a similar issue with two of our genes with not having HHPred results. Would we now call the genes called head to tail connector proteins initially and do not have HHPred results, NKF? We also have two other genes called head to tail connector protein. Although, with the new approved function list, the portal protein is used for Head to Tail connector but is only called by HHPred but not by blast and synteny so is it assumed that we use portal protein or also call this NKF beings blast and synteny call Head to Tail connector?
