In reviewing the CDD and HHpred for the Squint_196 Pham 25322 there is evidence that this protein is like the T4 immunity protein that sits in the plasma membrane and prevents superinfection. The Squint protein has three transmembrane helices. Is it possible to call this as an immunity protien or as imm. Admittedly the HHpred is only about half of the protein, but the combination makes it seem like this is a reasonable call.
