XB-FEAT-852929

chn2

This is the community wiki page for the gene chn2 please feel free to add any information that is relevant to this gene that is not already captured elsewhere in Xenbase

nomenclature changes

Based on reciprocal best BLASTp matches and synteny, the symbols for XB-GENEPAGE-852929 (chn1/chimerin 1) and XB-GENEPAGE-950873 (chn2/chimerin 2) were incorrectly assigned ie switched around. That is, XB-GENEPAGE-852929 should have been called chn2/chimerin 2 and XB-GENEPAGE-950873 should have been called chn1/chimerin 1.

The CHN2 gene sits at CREB5>...TRIL<...CPVL<...CHN2>...PRR15>...WIPF3>...SCRN1< in all other gnathostomes

So Xtrop GeneID: 100496459 and Xla.L GeneID: 444340 on chromosome 6 are CHN2 (supported by BLASTp too).

The CHN1 gene sits at ATP5MC3/G3>...ATF2>...CHN1>...CHRNA1>...WIPF1> in all osteichthyes except frogs which have just one-sided synteny of ATP5MC3/G3>...ATF2>...CHN1>...RBM45>...OSBPL6>...PRKRA<.  

So Xtrop GeneID: 100038142, Xla.L GeneID: 380027 and Xla.S GeneID: 108703013 on chromosome 9 are CHN1 (supported by BLASTp too).
