Although hPR-B shares many important structural domains with hPR-A, they are in fact two functionally distinct transcription factors, mediating their own response genes and physiological effects with little overlap.
AMalia que o hPR-B comparte moitos dominios estruturais importantes co hPR-A, en realidade ambos son dous factores de transcrición funcionalmente distintos, que median os seus propios xenes de resposta e efectos fisiolóxicos con poucas coincidencias.
