Subject: Re: TAK-1 mapping Dear Gillian . There is a gene which appears as JNKK2 (FBgn0040310), which BLAST shows to be the same as MKK4 (CG9738; FBan0009738). It seems to me that MKK4 is a better name and, whenever possible, it should be corrected (I guess). .

When deciding which gene symbol 'wins' (and becomes the valid FlyBase symbol) when merging 2 genes, we go for the symbol that was published first (including in GenBank records). I checked and Mkk4 will be the valid symbol as it was used first in a GenBank record in 1997. . Gillian
