Molecular characteristics of hagfish GPH. Alignment of the amino acid sequences of vertebrate GPHα (A) and GPHβ (B) subunits. Gaps are inserted to minimize alignment of Cys (C) residues among GPHα subunits, and between hagfish GPHβ and lamprey GTHβ, and FSHβ, LHβ, TSHβ subunits of fish species. The two sequences of hagfish GPH are indicated with blue letters and Cys residues that are conserved for all of these sequences are shown with red letters. Putative N-glycosylation sites are indicated by asterisks. The DDBJ/EMBL/GenBank accession numbers of amino acid sequences used for the alignment are as follows: (A) Shark GPHα (AJ310342), Sturgeon GPHα (AJ310343), and Lungfish GPHα (AB050093); (B) Lamprey GTHβ (AY730276), Shark FSHβ (SCA310344), LHβ (AJ310345), Sturgeon FSHβ (AST251658), LHβ (AJ251656), TSHβ (AJ251659), and Lungfish FSHβ (AJ578040), LHβ (AJ578038), and TSHβ (AJ578039).
