Prolactin-dependent signaling occurs as a result of a ligand-induced dimerization of the PRLR[1]. Relevance The signaling action of PRLR/prolactin complex serve to control the pattern of gene expression that contributes to breast development and the pathobiology of breast cancer[2]. Structural highlights (PDB code 3mzg). The interaction between PRLR and prolactin is strongly pH-dependent and is critically dependent on [3]. .
