Xenopus gene name changed from LOC100490615, lutropin subunit beta-like to lhb, luteinizing hormone subunit beta.
LOC100490615 (GeneID: 100490615, XP_002939281.1, XB-GENE-29080259) and lhb (GeneID: 100038205, XP_002939280.1, XB-GENE-486113). These two genes are adjacent to each other.

Best alignment of X. tropicalis 137 aa XP_002939281.1 is to 141 aa human LHB protein NP_000885.1. Best alignment of X. tropicalis 332 aa XP_002939280.1 is to 334 aa human SAXO3 protein NP_001382940.1.
Based on protein alignment and synteny, GeneID: 100490615/XB-GENE-29080259 is the ortholog of human LHB and GeneID: 100038205/XB-GENE-486113 is the ortholog of human SAXO3.
Xenopus tropicalis GeneID: 100038205/XB-GENE-486113 is also being changed from lhb to saxo3.
"X. laevis genes Gene D:108696760 [currently hb.2.L ] and GeneID:373843 [currently lhb.L ] need to be assesed.
