The identity of this gene and similar geens was assessed by David Webb from NCBI and Xenbase curators.

Based on synteny and reciprocal BALSTp matches to Human, this gene is now recognized as the true Xenopus orthologue of human B3GALT2.

In all gnathostomes,and in caecilians too, the B3GALT2 gene sits inside and intron of CDC73on the opposite strand IE., [ CDC73(...B3GALT2>)<...GLRX2>...RO60<...UCHL5> (FOR EXAMPLE SEE HUMAN GENEID:8707). Although the neighboring gene order is somewhat shuffled in the amphibians ( Nanorana and Xenopus), the b3galt2 gene still sits inside of cdc73.

Consequently, Entrez GeneID:100380178 is now seen to be a like gene, one of up to nine different b3galt2-like genes downstream of ilf3 on Xenopus chromosome 3.

David Webb notes that most reptiles, amphibians and basal mammals also have a few B3GALT2-like genes downstream of LIF3 gene ( e.g., see GeneID:115080934) but the genes seem to be frequently lost or unannotated.
