Dickkopf ?!?

Guess what my lab report is on ? Well, its on the Dickkopf-like protein 1 which is also known as Soggy ... what kinda protein name is that ? Its as if they couldnt think of anything and just decided to call it something really off. The whole Dickkopf i sorta understand since its from the testis ... DICKkopf and testis - i see a relation there. Soggy ??? Maybe the guy wanted to name it as saggy but decided on soggy since it would be more scientific.

This lab report sucks. Help ?!?
