The experiment is now to remove (by cloning) the corresponding repeat from that database protein, and to check what is the phenotypic change that that causes.

Unfortunately, the neraest database hits are not very close in terms of sequence identity in the low complexity motif. But if you get desperate, this is your best shot at this time.

And if you don not understand why I call it a SINQ repeat and not a QSIN repeat, well, sorry, but that is just as correct. Till we know what it does and how it does it, it will be difficult to come up with a good name anyway.

You can also read in the SwissProt file for Lica2: "Between 2 and 19 copies of the INQS repeats are to be found in different strains; these are thought to serve to generate phase-variable expression of this gene" but that tells what happens, but does not explain how it happens...
