If you found it, give it a name! I suggest "Fred". :-)

Unfortunately people have already named things, and most people would be quite
confused if the names were changed. Perhaps you can propose a consistent
system though, like what the chemists have done!

Yes. The chemists seem to be on the way though!

Yes. However, if one uses the species name as part of the label, then all
names withing the scope of the species can be consistent. In this way, we
introduce the concept of variable scope from computer languages into our
problem. This is the way people do it anyway, to it is not really a big

Well, we can just start making a list. Ribosome binding sites are always
the first on my list, but really promoters should be, then there's...
There are problems with the way GenBank assigns these things. For example,
they assign specific ranges to binding sites, whereas this may not be supported
by the data. That is, conservation (as measured by the information content)
can be outside the defined range. I think it is better to give a zero base,
but one must also give the orientation on the sequence. At least the
present method works, though it is not great.

Some groups name open reading frames orf1, orf2... But I think the folks
working on drosophila have a neat idea, and the names there are pretty nifty
(futz, bicaudal, etc). How about naming the genes after the streets in your
home town? The point is that although name tags are easy to remember, but are
really just arbitrary strings. Z? why lacZ? I don't know! But you and I
both know how different that is from lacI or lacY!
