Junfeng Chen et al. examine potential functional consequences of reproduction timing-associated TSHR alleles segregating in Atlantic herring. By comparing fish that spawn during the spring to those that spawn in the autumn, they find that the spring-allele is correlated with enhanced cAMP signaling and that both coding and non-coding variants in the TSHR locus contribute to seasonal reproduction.
