Relaxin-3/RXFP3 signaling within the central amygdala contributes to yohimbine-induced reinstatement of alcohol seeking. We therefore suggest that the relaxin-3/RXFP3 system represents a legitimate potential target for the treatment of both anxiety and substance use disorders.

the relaxin-3 B-chain C-terminus changes from the original folding-back conformation to an extended conformation during binding with RXFP3, to allow its B27Trp and B26Arg residues to interact with the Trp138 and Glu141 residues of RXFP3, respectively.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
