YWHAH proteins are adapter proteins in multiple signaling pathways that recognize phosphoserine or phosphothreonine motifs and regulate chaperone activity upon binding. It negatively regulates PDPK1 kinase activity and interacts with nuclear hormone receptors (AR, ESR1, ESR2, MC2R, NR3C1, NRIP1, PPARBP, THRA) and cofactors. 14-3-3 eta Protein, Human (GST) is the recombinant human-derived YWHAH protein, expressed by E. coli , with N-GST labeled tag.
