Upon ligand binding, receptor homodimerization or heterodimerization occurs, which is followed by autophosphorylation and activation of the tyrosine kinase domains.
This mechanism involves sequential actions of E2, P4, IFNT, CSH1 and GH1 with biological actions of CSH1 being mediated by homodimerization of the PRLR or heterodimerization of the PRLR and GH1 receptor (Noel et al.
The binding of a ligand causes activation and conformational change of the protein and homodimerization through phosphorylation.
To illustrate the practice of this invention, we have induced: (1) the intracellular aggregation of the cytoplasmic tail of the zeta chain of the T cell receptor (TCR)CD3 complex thereby leading to signaling and transcription of a reporter gene, (2) the homodimerization of the cytoplasmic tail of the Fas receptor thereby leading to cell-specific apoptosis (programmed cell death) and (3) the heterodimerization of a DNA-binding domain (Gal4) and a transcription-activation domain (VP16)
